Updates the ClickHouse chat agent example page to match the upgraded
example (triggerdotdev/examples#124), which is now a fullstack
generative-UI chat app rather than an agent-only project.
## What changed
- **Overview / tech stack / features** rewritten: Next.js chat app
(`useChat` + `useTriggerChatTransport`, no API route), a
`renderVisualization` tool taking json-render specs rendered with
`@json-render/shadcn` + shadcn charts (Recharts) + mapcn point maps, and
a shared catalog that generates both the system-prompt component
reference and tool-call validation.
- **The agent section** now shows the versioned [AI
Prompt](https://trigger.dev/docs/ai/prompts) pattern (`prompts.define()`
+ `chat.prompt.set()` + `chat.toStreamTextOptions({ registry })`), with
a warning that `experimental_telemetry` comes from the stored prompt —
the docs previously showed a static `system:` string, which silently
ships no LLM observability.
- **New sections** for the shared catalog, the `renderVisualization`
tool, the Next.js chat UI and registry.
- **Relevant code links** updated to the new `src/` layout.
- **Learn more** cards now include Frontend and AI Prompts.
Note: merge after triggerdotdev/examples#124 lands, so the GitHub file
links resolve.

## Summary
When the run-ops split is enabled, the legacy run-ops database client
was always constructed as its own connection pool, even when it points
at the same database as the primary (control-plane) client. On setups
where those two DSNs resolve to the same physical database, this opened
a second, redundant pool and doubled the number of connections used
against that database. This change makes the legacy client reuse the
primary client's pool whenever their DSNs point at the same database,
and only open a separate pool when they genuinely differ.
## Fix
A small `sameDatabaseTarget` comparison (host, port, database name,
user) decides whether the legacy DSN points at the same database as the
primary. When it does, the legacy handle reuses the primary client by
reference, so no second pool is opened. When the DSNs diverge, the
legacy client is built independently as before, so the split still works
once the databases are actually separate.
Two smaller changes ride along:
- An optional per-pool limit for the run-ops read replica, which
connects unpooled and so draws raw backend connections; unset, it falls
back to the existing default and behaviour is unchanged.
- A startup warning about a missing legacy replica URL is now suppressed
when the legacy client shares the primary pool, where it would be
misleading.
## Verification
Booted the webapp end-to-end in three modes and confirmed the pools
opened as expected via the client's own startup logs and live backend
connection counts: split off (single pool), split on with a shared
database (legacy reuses the primary pool, no doubling), and split on
with separate databases (legacy opens its own pool).
## Summary
2 new features, 11 improvements, 5 bug fixes.
## Breaking changes
- Trigger.dev v3 is no longer supported. For self-hosted deployments,
4.5.0 is the last version we officially support for running v3; stay on
4.5.0 or upgrade to v4. v3 triggers, batch triggers, reschedules, and
deploys now return a clear upgrade message instead of running.
([#4236](https://github.com/triggerdotdev/trigger.dev/pull/4236))
## Improvements
- You can now mark environment variables synced via the `syncEnvVars`
build extension as secrets. Return `{ name, value, isSecret: true }`
from your callback and those variables are stored redacted in the
dashboard, just like manually created secret env vars.
([#4203](https://github.com/triggerdotdev/trigger.dev/pull/4203))
- Remove the legacy `--mcp` and `--mcp-port` options from the `dev`
command. Run the dedicated `trigger mcp` command to start the
Trigger.dev MCP server.
([#4246](https://github.com/triggerdotdev/trigger.dev/pull/4246))
- Removed the unused `ResourceMonitor` export from
`@trigger.dev/core/v3/serverOnly`. It was a server-side logging helper
with no remaining consumers.
([#4244](https://github.com/triggerdotdev/trigger.dev/pull/4244))
- Removed the unused `@trigger.dev/core/v3/zodNamespace` export and the
legacy v3 socket message schemas. These were only used by the
now-retired v3 engine and have no v4 consumers.
([#4236](https://github.com/triggerdotdev/trigger.dev/pull/4236))
## Bug fixes
- Fix a `chat.agent` message-loss race where sending a message right
after an action (such as an undo) could drop the follow-up's response
from the UI until a refresh.
([#4234](https://github.com/triggerdotdev/trigger.dev/pull/4234))
## Server changes
These changes affect the self-hosted Docker image and Trigger.dev Cloud:
- Added `EVENT_REPOSITORY_POSTGRES_WRITES_DISABLED` to skip all
PostgreSQL task-event writes for deployments that store task events in
ClickHouse. Leave it off unless `EVENT_REPOSITORY_DEFAULT_STORE` is
`clickhouse_v2`, otherwise task events are lost.
([#4242](https://github.com/triggerdotdev/trigger.dev/pull/4242))
- Promo credits: a /promo signup landing page, redeeming a promo code
when a new org selects a plan, and showing remaining credits on the
usage page.
([#4138](https://github.com/triggerdotdev/trigger.dev/pull/4138))
- Speed up retrieving a background worker by version. The endpoint no
longer runs a slow lookup that scanned the full task table for large
deployments; it now reuses data it already loads, so the response is the
same but returns much faster.
([#4245](https://github.com/triggerdotdev/trigger.dev/pull/4245))
- Clearer login error when an email address is blocked by the
WHITELISTED_EMAILS setting: the message now explains the address isn't
allowed on this instance instead of the ambiguous "This email is
unauthorized".
([#4220](https://github.com/triggerdotdev/trigger.dev/pull/4220))
- Make the native build server the default in project build settings.
It's now opt-out, stored as a new `disableNativeBuildServer` key. Also
clarifies in the UI that build settings apply to GitHub-triggered and
native build server deployments.
([#3980](https://github.com/triggerdotdev/trigger.dev/pull/3980))
- Optionally process high-volume telemetry ingestion in parallel for
higher throughput under heavy load by setting
`OTEL_TRANSFORM_WORKER_POOL_ENABLED=1`. Off by default.
([#4232](https://github.com/triggerdotdev/trigger.dev/pull/4232))
- Add a `REALTIME_BACKEND_DEFAULT` env var to choose the default
realtime backend (`electric`, `native`, or `shadow`) for environments
whose org has no per-org override. Defaults to `electric`, so existing
behavior is unchanged.
([#4231](https://github.com/triggerdotdev/trigger.dev/pull/4231))
- Clarified on the Regions page that a region only affects where your
runs execute, not where your data is stored. This shows as a tooltip on
the Location column and in the confirmation dialog when you change your
default region.
([#4226](https://github.com/triggerdotdev/trigger.dev/pull/4226))
- Improved the reliability of how run data is read and written.
([#4237](https://github.com/triggerdotdev/trigger.dev/pull/4237))
- Fixed stale login errors: an error from a previous login attempt (for
example a rejected email address) no longer keeps reappearing on the
login page and no longer makes later, successful attempts look like they
failed.
([#4220](https://github.com/triggerdotdev/trigger.dev/pull/4220))
- The Errors page now shows better details for each error. Errors that
don't carry a message — such as errors thrown without a message, or
values thrown that aren't `Error` objects — get a meaningful title
instead of all reading "Unknown error", and are grouped by their name
(or value) rather than collapsed into a single group. The error type now
shows the actual error name, and stack traces now appear where
previously they were missing.
([#4225](https://github.com/triggerdotdev/trigger.dev/pull/4225))
- Return a clear client error when SSO form submissions use an
unsupported content type
([#4238](https://github.com/triggerdotdev/trigger.dev/pull/4238))
- Query page: extracting fields from a run's output with JSON functions
(such as JSONExtractString or JSONExtractInt) no longer fails with an
"illegal type: JSON" error.
([#4221](https://github.com/triggerdotdev/trigger.dev/pull/4221))

The dashboard was redesigned and two pages moved, but the docs still
described the old sidebar:
- **Schedules** no longer has its own sidebar page — schedules are
managed from the **Tasks** page (open a scheduled task to create / view
/ edit / enable-disable / delete them).
- The standalone list-based **Test** page is deprecated — you test a
task from its own **Test** button now.
## Changes
- `tasks/scheduled.mdx`: rewrote the "attaching schedules" and "testing
schedules" sections for the Tasks-based flow, added a "managing
schedules in the dashboard" section, and added explicit callouts noting
both pages moved (so readers — and search — aren't pointed at a page
that no longer exists). Re-shot the four schedule screenshots and fixed
a mislabeled alt text.
- `run-tests.mdx`, `snippets/step-run-test.mdx`,
`guides/examples/sentry-error-tracking.mdx`: replaced "select the Test
page in the sidebar" with the task-first flow plus a callout, and
refreshed `test-dashboard.png`.
TRI-11939
The `ResourceMonitor` server-side logging helper is no longer used. It
periodically logged the webapp process own memory, disk, and CPU usage
behind the `RESOURCE_MONITOR_ENABLED` flag (off by default), and was
also exported from `@trigger.dev/core/v3/serverOnly` with no other
consumers.
This removes the helper, its `@trigger.dev/core` export, the webapp
wiring, and the `RESOURCE_MONITOR_ENABLED` env var. The supervisor has
its own unrelated `ResourceMonitor` class, which is left untouched.
## Summary
Adds `EVENT_REPOSITORY_POSTGRES_WRITES_DISABLED` (default off), which
makes the task-event store skip all PostgreSQL `TaskEvent` writes. It's
for deployments that store task events in ClickHouse
(`EVENT_REPOSITORY_DEFAULT_STORE=clickhouse_v2`) and no longer want the
PostgreSQL copy.
## How it works
The guard sits at the single postgres write boundary,
`TaskEventStore.create` / `createMany`, so it covers every write path
(OTLP ingestion and run-lifecycle events) with one check. Reads are
untouched (`findMany` / trace queries / streaming), so existing
PostgreSQL events remain readable.
Leave it off unless the default store is `clickhouse_v2`, otherwise task
events for any run still routed to PostgreSQL would be dropped.
## What
The `GET
/api/v1/projects/:projectRef/background-workers/:envSlug/:version`
endpoint loaded each file's tasks through the nested `files.tasks`
relation. Prisma resolves that as a separate query:
```sql
SELECT id, slug, "fileId" FROM "BackgroundWorkerTask" WHERE "fileId" IN (...)
```
`BackgroundWorkerTask.fileId` is not indexed — the FK constraint exists,
but Postgres does not auto-create an index for foreign keys — so on a
large table this can only run as a sequential scan, which gets
progressively slower as the table grows and was observed taking minutes
per call in production.
The loader already loads every task for the worker via `tasks: true`,
which uses the indexed `workerId` relation, and those rows already
include `fileId`. This PR groups task slugs by `fileId` in memory from
that already-loaded data and drops the `files.tasks` include entirely.
## Behavior change (latent bug fix)
The response shape is unchanged, but there is a semantic correction for
**source files reused across worker versions** (files are de-duplicated
by `@@unique([projectId, contentHash])`, so one file row can be linked
to many workers).
- **Before:** `file.tasks` came from the `BackgroundWorkerFile.tasks`
relation, i.e. *every* `BackgroundWorkerTask` with that `fileId` —
across all workers sharing the file. So a worker's manifest could list
tasks it doesn't actually have.
- **After:** `file.tasks` is grouped from the queried worker's own
tasks, so it reflects only that worker version's tasks.
Verified on a local DB: 460 files are referenced by tasks from more than
one worker; of 6819 (worker, file) pairs, 6 differ — all one file where
the old union leaked a task slug (`cancellation-test`) into worker
versions that never had it. The new per-worker behavior is the correct
one for a worker-version manifest. (Thanks to the automated review for
flagging this.)
## Analysis
Captured the exact SQL before/after by instrumenting Prisma against real
data (a worker with 62 files):
- **Before:** 5 statements, including the `WHERE "fileId" IN (...)`
scan.
- **After:** 4 statements; the `fileId` query is gone and the other four
are identical.
EXPLAIN of the two access paths:
```
Before WHERE "fileId" IN (...)
Seq Scan on "BackgroundWorkerTask"
Filter: ("fileId" = ANY (...)) -- reads the whole table, scales with table size
After WHERE "workerId" IN (...)
Index Scan using "BackgroundWorkerTask_workerId_slug_key"
Index Cond: ("workerId" = ...) -- bounded by matching rows, scale-independent
```
No new index is required: the `workerId` access path is already covered
by the existing `BackgroundWorkerTask_workerId_slug_key` unique index.
## Testing
- `pnpm run typecheck --filter webapp` passes.
- Query capture + EXPLAIN performed against a local database seeded with
real worker/file/task data.
Routine dependency maintenance.
- Pin a few high-fanout transitive deps to current patched versions via
`pnpm.overrides`: `form-data`, `ws`, `undici`, `hono`. Lockfile-only (no
published-package dependency changes); net shrinks via dedup.
- Upgrade `nodemailer` 8 → 9 in `internal-packages/emails` (private
package). The SES transport already uses SESv2 and the
`createTransport`/`sendMail` API is unchanged, so no code changes were
needed. `@types/nodemailer` stays at 8 (no 9.x published yet; types are
compatible).
Verified locally: `pnpm i` clean; `pnpm run typecheck --filter emails`
and `--filter webapp` both pass.
## Summary
Run-graph data (runs, batches, waitpoints, and their related tables) can
now live in a database separate from the control plane, with every read
and write routed to the correct database by each run's residency. This
makes reading and writing run data more reliable once the two are split,
and is a no-op for single-database installs.
## Design
- Run-graph table access goes through the run-store router, which
selects the legacy or the new run-ops store per run instead of assuming
one shared client.
- The legacy run-ops client is now independently pointable, so legacy
run data can be served from its own database (and replica) rather than
the control-plane connection.
- Run-graph writes go straight to the run-graph database instead of
being forwarded through the control plane, and replication targets are
split so runs in the new database still replicate to analytics without
under-counting.
- Read-through slots refuse the control-plane client, so a missing
residency fails loudly instead of silently reading the wrong database.
- Migration `20260710120000_drop_remaining_run_graph_seam_foreign_keys`
drops the foreign keys that still crossed the run-graph / control-plane
seam, which is what lets the two live in separate databases.
The split stays off unless explicitly enabled and the two databases are
confirmed physically distinct; startup fails closed otherwise.
Verified by running the full dashboard end-to-end suite against both a
single-database configuration and a three-database configuration
(control plane, the new database, and a physically separate legacy
database), with runs on both residencies. No misrouted reads in either
configuration.
## Summary
Refreshes the docs for the v3 sunset: v3 (SDK v3) is end of life, and
4.5.0 is the last version we officially support for running v3.
- The self-hosting overview, plus the docker and kubernetes
version-locking sections, now tell self-hosters on v3 to stay on 4.5.0
or migrate to v4. 4.5.1 and later reject v3 triggers and deploys with an
upgrade message.
- The migration guide's deprecation notice was still written in the
future tense (with dates that have since passed); it now describes v3 as
retired and adds the self-hosted 4.5.0 cutoff. This is the page the
server's upgrade message links to.
- Fixes a stale "v3 project" reference in the CLI overview.
The Mintlify preview will render the callouts for a visual check.
## Summary
v3 (the engine that ran the SDK v3 era, internally
`RunEngineVersion.V1`) is end-of-life. Following the removal of the v3
execution apps
([#4194](https://github.com/triggerdotdev/trigger.dev/pull/4194)) and
the legacy dev websocket
([#4198](https://github.com/triggerdotdev/trigger.dev/pull/4198)), this
removes the remaining v3 execution stack from the server.
Clients still on v3 (an old SDK or CLI that has not upgraded) keep
getting a clear "upgrade to v4" response. Triggers, batch triggers,
reschedules, and deploys that resolve to v3 are rejected with a graceful
4xx pointing at the migration guide, never a 5xx, so a stale client
cannot affect server health. Self-hosted instances still running v3
should stay on the 4.5.x release line until they migrate.
## What is removed
- The MarQS queue and its shared/dev queue consumers.
- The v3 socket.io namespaces (coordinator, provider, shared-queue) and
the v3 run lifecycle services (attempt, checkpoint, and batch-resume).
- The graphile-worker background job system; all live jobs already run
on `@trigger.dev/redis-worker`.
- The `DEPRECATE_V3_ENABLED` flag: v3 is now rejected unconditionally,
so the flag is gone.
- Unused v3 exports from `@trigger.dev/core` (the `v3/zodNamespace`
subpath and the legacy socket message catalogs) and the now-dead MarQS
environment variables.
## What stays
The v4 engine is untouched. The graceful v3 rejection boundary stays,
`determineEngineVersion` still detects a v3 project so it can reject it,
and the batch service plus batch-completion worker stay for current
clients. Live queue concurrency limits and metrics now read from the v4
run engine instead of MarQS, and a brand-new dev environment now
defaults to v4.
## Dependency cleanup
Removes webapp dependencies left unused by this change: `seedrandom` and
`semver` (only the removed v3 code used them) plus a set that was
already dead, their orphaned `@types` packages, and two dead files. Adds
a `knip:deps` script and a `knip.json` config so unused dependencies can
be found the same way going forward.
## Summary
Two threads on the run-ops split path.
Read path: per-item run reads are batched into grouped queries, a
waitpoint's connected-run reads are bounded, and the dedicated-schema
relation hydrators fetch only the requested columns instead of whole
rows. Retrieve also falls back to the other database when a routed read
misses, so a run whose physical residency diverges from its id shape is
still found rather than returning a spurious not-found. Fewer and
lighter queries on the run read path, with no change to results.
Mint-kind flip safety: flipping which database new runs mint to is now a
deterministic wall-clock cutover, for both per-org and global flips. For
a grace window every process resolves the same database, so a flip
cannot route two concurrent triggers that share an idempotency key to
different databases (which would bypass the per-database unique
constraint and create a duplicate run).
Supersedes the earlier #4205 and #4208.
Draft: validation in progress.
Switches the native build server from opt-in to opt-out in project build
settings.
- It's now enabled by default, stored as a new
\`disableNativeBuildServer\` opt-out key so previously-saved
\`useNativeBuildServer: false\` values aren't treated as deliberate
opt-outs.
- The "Use native build server" checkbox is checked by default;
unchecking it persists the opt-out.
- Brief wording: clarifies build settings apply to GitHub-triggered and
native build server deployments, and the native build server hint no
longer says "in the future".
## Summary
Under high OTLP ingest volume, the whole decode, transform, and enrich
pipeline runs on the request event loop, so a single CPU core becomes
the ceiling while the rest sit idle. This adds an opt-in worker pool
that moves decode, transform, and LLM-cost enrichment onto worker
threads, keeping the main thread free for I/O. It is off by default
(`OTEL_TRANSFORM_WORKER_POOL_ENABLED`), so behavior is unchanged unless
enabled.
## Design
Workers do decode, filter, convert, and enrich (including LLM pricing
match). The main thread stays the single database reader: it loads the
pricing registry and broadcasts the compiled model rows to the workers
(re-broadcasting on every reload), so workers never touch the database.
The pure transform is extracted into a dependency-light module (no
Prisma/Redis/ClickHouse imports) so it can run inside a worker.
Importantly, the main thread keeps the existing single consolidated
insert path, so ClickHouse insert batching and part count are unchanged.
The parallelism buys CPU headroom, not more insert streams (which would
add merge pressure).
The worker is bundled as a standalone file at build time and ships in
the existing image with no Dockerfile change. In local load testing the
pool sustained roughly 2.6x the throughput of the single-thread path and
kept the main thread responsive under load.
## Summary
Sending a chat message immediately after an action (for example an undo)
could make the message's response vanish from the UI. The transport
opened a response stream that closed on the *earlier* turn's completion
instead of waiting for the send's own turn. The agent still produced and
persisted the answer, so it reappeared on refresh. Same "disappearing
message" class as
[#4176](https://github.com/triggerdotdev/trigger.dev/pull/4176),
different cause.
## Fix
A send's response stream had no way to tell whether a `turn-complete`
belonged to its turn. `POST /realtime/v1/sessions/:id/in/append` now
returns the appended record's sequence number, and the transport skips
any turn-complete whose `session-in-event-id` (the agent's committed
`.in` cursor) is below that seq, closing only on its own turn. Older
webapps omit the seq, in which case the transport falls back to the
previous behavior, so the SDK and server can ship independently.
Because the fix spans the SDK and the server, both a webapp deploy and
an SDK release are needed for the full effect.
Verified end to end with the ai-chat reference app:
undo-then-immediate-send loses the follow-up's answer before the fix and
streams it inline after, with a revert-the-guard run reproducing the
loss on the same script. Unit tests cover the skip and the no-seq
fallback.
## Summary
The default realtime backend was hardcoded to Electric. This adds a
`REALTIME_BACKEND_DEFAULT` env var (`electric` | `native` | `shadow`,
default `electric`) that chooses the backend for any environment whose
org has no `realtimeBackend` override. Behavior is unchanged unless you
set it; per-org overrides still win.
The default is applied at every point where the per-org flag falls
through: the initial value, the flag lookup default, and the error
fallback.
## Problem
Several display/grouping issues in the **Errors** feature, all rooted in
how the ClickHouse error materialized views (`errors_mv_v1`,
`error_occurrences_mv_v1`) read the stored error JSON produced by
`parseError`:
1. **Messageless errors show "Unknown error".** An empty message falls
straight through `coalesce(nullIf(message,''), 'Unknown error')` to the
literal, even though the error's class `name` is available (e.g. an
Effect tagged error `ListMessagesError` with no message).
2. **Unrelated errors collapse into one group.**
`calculateErrorFingerprint` keys on `type : message : stack`, where
`type` is always the union tag (`BUILT_IN_ERROR`, …), `message` is
empty, and the stack isn't read — so every messageless built-in error
(and every string/custom error) hashes to the same constant input → one
fingerprint.
3. **error_type shows the internal tag.** `coalesce(type, name, …)`
always resolves to `type` (always present), so the column shows
`BUILT_IN_ERROR` instead of the real class name.
4. **Stack traces never populate.** The MVs read `error.data.stack`, but
the serializer stores the trace under `stackTrace` — so the column is
always empty.
## Fix
All display changes are `ALTER TABLE … MODIFY QUERY` on the two views
(migration `035`); the fingerprint change is in the webapp.
- **Fingerprint** (`errorFingerprinting.ts`): fall back **message → name
→ raw**. Messageless errors now group by class name (or raw value for
non-Error throws); message-bearing errors are **unchanged**
(short-circuits at `message`), so existing groups don't split — only
currently-messageless errors get their own group going forward.
- **error_message**: same `message → name → raw` fallback before
`'Unknown error'`.
- **error_type**: coalesce `name → code → 'Error'` (drops the reliance
on the union tag). Built-in → class name, internal → `code`,
string/custom → `Error`.
- **stack trace**: read `error.data.stackTrace`. Bounded as before
(serializer caps 50 frames / 1024 chars per line; MV clips to 2000
chars).
## Migration notes
- `MODIFY QUERY` swaps the view query in place (no drop/recreate gap);
Down restores the previous query.
- **Existing rows are left unchanged** — changes apply only to rows
inserted after the migration. No backfill.
## Tests
`errorFingerprinting.test.ts` — 57 pass, incl. new cases for messageless
class names, string/custom raw values, and stability of message-bearing
fingerprints.
Fixes the display-derivation half of TRI-11938 (error_type + stack
trace); relates to TRI-9254 and TRI-9250.
Applying a directory-sync effect that would demote the org's last Owner
(a
group remap, or a provision) previously threw and 500'd the settings
save. Now
rbac.setUserRole reports code:"last_owner" and applyEffect skips just
that
member (they keep Owner) while the rest of the batch applies.
Adds the machine-readable RoleAssignmentResult.code to the plugin
contract so
callers can tell the last-owner guard apart from a real failure.
## Summary
The RBAC and SSO auth plugins can own their own database client, but
they could only read `DATABASE_URL`, so every connection they opened
landed on the primary. The host webapp now resolves writer and
read-replica URLs from its env (the same fallback chain its own Prisma
clients use: control-plane URL first, then the default) and passes them
to the plugins at create time via a shared `PluginDatabaseConfig`, along
with separate connection limits for writes (default 2) and reads
(default 5, tunable via `RBAC_DATABASE_*_CONNECTION_LIMIT` and
`SSO_DATABASE_*_CONNECTION_LIMIT`).
A plugin can then route hot-path reads (per-request auth checks, login
routing) to the read replica and keep only rare mutations on the
primary. With no replica configured, or no plugin installed, nothing
changes: the OSS fallback ignores the new option and keeps reading
through the Prisma clients it is already given.

## Summary
This adds an always-visible info tooltip on the Location column and a
note in the "set default region" confirmation dialog making it explicit.
It also removes the obsolete "V4" badge from the Regions page title.
## What & why
Signup promo credits. A new logged-out `/promo?code=<code>` landing page
validates the code and carries it through signup via a cookie. When the
new organization is activated by selecting a plan, the code is redeemed
and its credits are applied; the usage page then shows the remaining
promo credits and their expiry.
## Notes
- The code is redeemed at **plan selection**, not org creation: the
credit grant targets the org's usage allowance, which only exists once a
plan is selected — applying at creation would have nothing to grant
onto. Redemption is best-effort and never blocks plan selection.
- Pairs with the corresponding billing-service change (promo code
validate/apply/credits + grant issuance); the two are released together.
## Testing
Verified locally end to end: `/promo` shows the offer, a new account
carries the code through signup, selecting the Free plan redeems it, and
the usage page shows the remaining credits.

## What
Adds per-variable secret support to the `syncEnvVars` build extension.
Return `{ name, value, isSecret: true }` and the variable is stored as a
secret (redacted in the dashboard, value non-revealable), just like a
manually created secret env var. Secret and non-secret variables can be
mixed in one callback.
```ts
syncEnvVars(async () => [
{ name: "PUBLIC_API_URL", value: "https://api.example.com" },
{ name: "DATABASE_URL", value: "postgres://...", isSecret: true },
]);
```
## How
Env vars flow through the build pipeline as a flat name→value map, and
the import API's `isSecret` is per-call. So secret vars are carried
through the layer + manifest in parallel `secretEnv` / `secretParentEnv`
maps, and at deploy time they go up in a second `importEnvVars` call
with `isSecret: true` (the plain vars in the first call). The record
form (`{ KEY: "value" }`) is unchanged and stays non-secret.
## Commits
- `feat(core)`: carry secret env vars through the build layer + manifest
schema
- `feat(build)`: partition `isSecret` vars in `syncEnvVars`
- `feat(cli)`: merge secret layers and import them with `isSecret: true`
at deploy
- `test(build)`: cover the partitioning + document `isSecret`
## Testing
- vitest covers the partitioning (secret/non-secret × child/parent) and
that the record form stays non-secret.
- Verified against a local webapp that the deploy's import contract
stores the secret var redacted (`isSecret: true`) and the plain var
visible.
Closes TRI-11099
Creating a Prisma migration now formats its schema first, keeping
migration-related schema edits consistently formatted without adding
work to the repository-wide format command. Run `pnpm run format:prisma`
to format either schema on demand.
## Summary
A Query page (TRQL) query that pulls fields out of a run's `output` with
JSON functions (`JSONExtractString`, `JSONExtractInt`, `JSONHas`, and
the rest of the family) failed with "The first argument of function ...
should be a string containing JSON, illegal type: JSON". Those queries
now work.
## Root cause and fix
`output` is a native ClickHouse `JSON` column, but `JSONExtract*`,
`JSONHas`, `JSONLength`, and `JSONType` all expect a String containing
JSON text. The compiler already swaps in the column's String companion
(`output_text`) when a JSON column is selected or compared, but not
inside function-call arguments, so it emitted `JSONExtractInt(output,
'x')` against the native column.
The fix prints the companion column for the first argument of these
functions when it resolves to a bare JSON field, keeping the table alias
when qualified (so it works in JOINs):
JSONExtractInt(output, 'x') -> JSONExtractInt(output_text, 'x')
JSONExtractArrayRaw(assumeNotNull(output), 'y') ->
JSONExtractArrayRaw(assumeNotNull(output_text), 'y')
It also reaches through value-preserving passthrough wrappers like
`assumeNotNull(...)`, while leaving value-changing wrappers like
`toJSONString(output)` on the native column (that argument is already a
String). The swap is also semantically correct, not just a type fix:
`output_text` is the unwrapped data JSON that the TRQL `output` model
already represents, so field paths line up.
Covered by printer unit tests and a ClickHouse integration test that
runs the whole family (plus the wrapped and `toJSONString` cases)
against a real native-JSON column. Both new cases fail with the exact
"illegal type: JSON" error without the fix.
## ✅ Checklist
- [x] I have followed every step in the [contributing
guide](https://github.com/triggerdotdev/trigger.dev/blob/main/CONTRIBUTING.md)
- [x] The PR title follows the convention.
- [x] I ran and tested the code works
---
## Testing
- Verified the rule emits exactly five errors for un-awaited throws of
the known
async redirect helpers while ignoring awaited throws, returned promises,
and
synchronous `redirect(...)`.
- Verified `--fix` inserts `await` in async functions and produces a
clean
second lint run.
- Verified synchronous functions remain diagnostic-only so autofix
cannot
introduce invalid syntax.
- Ran `pnpm run format`, `pnpm run lint`,
`pnpm run typecheck --filter webapp`, and `git diff --check`.
---
## Changelog
Adds an Oxlint rule that prevents async redirect helpers from being
thrown
without awaiting their `Response`. Existing violations are fixed, the
autofix
is limited to async functions, and the plugin uses an explicit ESM
extension.

- Combine SDK and dashboard bulk actions docs
- Fix API reference pages for bulk actions
- Fix weird rendering on bulk actions page
## Todo
- [ ] not sure about having the SDK+dashboard combined and under "Using
the dashboard"... need to find the right place
## Summary
The limits page didn't spell out that large payloads offload to object
storage automatically, and its single "512KB" note conflated two
different thresholds. This clarifies the behaviour.
On the way in, the SDK uploads any trigger or batch-item payload over
128KB to object storage before sending, so large triggers and batches
don't hit the request body limit (`trigger` / `triggerAndWait` since
4.5.0, `batchTrigger` / `batchTriggerAndWait` since 4.5.2). On
retrieval, payloads and outputs over 512KB are stored in object storage
and returned as a presigned URL from `runs.retrieve`.
## Summary
Magic link login could appear completely broken: submitting your email
on the login page showed a stale "This email is unauthorized" error
instead of the "we've sent you a magic link" confirmation, even when the
address was fine.
This PR reverts
[#4215](https://github.com/triggerdotdev/trigger.dev/pull/4215) (whose
diagnosis and fix turned out to be wrong) and fixes the actual bug,
which was in how login errors are stored and consumed.
## Root cause
Two session bugs compounded on the login page:
- The `/login` loader read the flashed `auth:error` without committing
the session. A Remix flash is only consumed when the session is
committed after the read, so once any attempt flashed an error (for
example an address rejected on an instance with `WHITELISTED_EMAILS`
set), it stayed in the session cookie and reappeared on every later
`/login` visit, making successful attempts look like failures.
- The `/login/magic` action stored its validation and rate limit errors
with `session.set`, which survives every later read and commit, so those
errors stuck permanently.
[#4215](https://github.com/triggerdotdev/trigger.dev/pull/4215) had
instead diagnosed a server-only module leaking into the client bundle
and crashing navigation. Checking the shipped images' client bundles via
their sourcemaps shows `.server` modules were always stubbed out, so
that change fixed nothing and is reverted here.
## Fix
- `/login` reads the flashed error and commits the session when one was
present, so an error renders once and clears. The `redirectTo` branch
now surfaces the error too instead of leaving it in the cookie.
- `/login/magic` flashes its errors instead of `set`ting them.
Verified end-to-end on a live preview environment: a rejected address
shows the error once and a reload clears it; a valid address lands on
the confirmation screen with the address named; GitHub, Google, and SSO
login paths are untouched by this diff.
## Summary
1 improvement, 2 bug fixes.
## Breaking changes
- Removed support for the end-of-life v3 `trigger dev` CLI. Starting a
dev session with an old v3 CLI now returns an upgrade message instead of
connecting - upgrade to the v4 CLI to continue using `trigger dev`.
([#4198](https://github.com/triggerdotdev/trigger.dev/pull/4198))
## Bug fixes
- Fix TS2742 ("inferred type cannot be named") when exporting a
`chat.agent` from a project with declaration emit: `ChatTaskWirePayload`
and `ChatInputChunk` are now declared in the public
`@trigger.dev/sdk/chat` subpath, so inferred agent types emit portable
declarations and the wire types are directly importable.
([#4218](https://github.com/triggerdotdev/trigger.dev/pull/4218))
## Server changes
These changes affect the self-hosted Docker image and Trigger.dev Cloud:
- Reduce primary database load on the runs page by serving its
empty-state check from ClickHouse instead of Postgres.
([#4202](https://github.com/triggerdotdev/trigger.dev/pull/4202))
- Fixed submitting your email on the login page reloading back to an
empty form instead of showing the magic link confirmation screen.

## Summary
Exporting a `chat.agent` from a project with `declaration: true` failed
with TS2742: the inferred type of the agent references
`ChatTaskWirePayload`, which was declared in an internal module not
reachable through the package exports map, so tsc could only name it via
a file path into `node_modules` and refused to emit. Consumers had to
hand-mirror the wire type and annotate their export.
## Fix
`ChatTaskWirePayload` and `ChatInputChunk` are now declared in
`@trigger.dev/sdk/chat` (a public subpath) and re-exported type-only
from the internal shared module, so every internal import is unchanged
and the browser/server module split is untouched. Declaration emit for
an inferred agent type now produces a portable specifier:
```ts
export declare const chatAgent: Task<"chat-agent", import("@trigger.dev/sdk/chat").ChatTaskWirePayload<MyUIMessage, MyClientData>, unknown>;
```
As a side effect the wire types are now directly importable, which is
what affected users were reconstructing by hand.
## Verification
Reproduced against the built 4.5.2-equivalent package: a consumer
fixture with declaration emit produced `import("<file
path>/ai-shared.js")` in its declaration (the TS2742 trigger); after the
fix the same fixture emits the public specifier with zero diagnostics. A
regression test now builds that consumer simulation in a temp directory
on every test run: it copies the built package into a fake node_modules
(copied, not symlinked, because tsc only applies exports-map naming to
real node_modules paths), compiles the fixture with the TypeScript API,
and asserts no errors, no relative-path imports, and no internal module
references in the emit.
## Summary
Submitting your email on the login page could reload back to an empty
login form instead of showing the "we've sent you a magic link"
confirmation. The magic link email was still sent, so it looked like
nothing happened.
## Root cause
The `/login/magic` route imported a server-only cookie module
(`magicLinkEmailCookie.server.ts`) whose top-level `env.NODE_ENV` read
got bundled into the route's client JS. On the client `env` is
undefined, so the module threw a `TypeError` at module eval, which
aborted Remix's client-side navigation to the confirmation and
hard-reloaded back to `/login`. It only surfaced in production builds
(local dev auto-logs-in, and local prod builds happen to tree-shake the
module out), which is why it slipped through.
## Fix
The email-link strategy already stores the submitted address in the
session (`auth:email`), so the separate cookie was redundant. Deleted
the cookie module and read the address from the session in the loader.
With the module gone, nothing server-only can leak into the client
bundle regardless of tree-shaking.
Verified the confirmation renders with the email address, the SSO
domain-policy redirect (with the email prefilled) still works, and a
production build no longer bundles the module.
Condense the kept rationale comments (logLevel/warn, last-Owner dedup,
role
overwrite) and drop the obvious function-header comments that just
restated
the code. No behavior change.
## Summary
Excludes the non-published plugins workspace from Changesets release
planning so it cannot drive public package version bumps.
## Verification
Ran `pnpm run changeset:version` with temporary changesets for
`@trigger.dev/plugins` and `@trigger.dev/core`; the ignored workspace
produced no release-driver updates, and the public package changeset
versioned normally.
Directory-sync effects are idempotent and the accounts-webhook worker
retries
the whole event, so a single failed attempt (typically a role assignment
losing a serializable race during a backfill burst) is self-healing
rather
than alert-worthy. Tag those thrown errors with logLevel "warn" so the
worker
logs at warn instead of error, keeping them visible for triage without
paging.
## Summary
The runs page's empty-state check (whether an environment has ever had a
run, which decides between the "getting started" and "no runs match your
filters" states) ran a `findFirst` against the Postgres `TaskRun` table.
This moves it to ClickHouse, the same store the runs list itself reads
from, so the check no longer queries `TaskRun`.
## Design
Only the runs list triggers the check now (via an `includeHasAnyRuns`
flag); the other presenters that reuse `NextRunListPresenter` (API,
schedule detail, waitpoint detail, error group) no longer issue it. When
the list is empty it runs `SELECT 1 FROM task_runs_v2 ... LIMIT 1`
filtered on the full `(organization_id, project_id, environment_id)`
sort-key prefix with a configurable `created_at` lower bound
(`RUN_LIST_HAS_RUNS_LOOKBACK_DAYS`, default 30), so it hits the primary
index and reads minimal granules.
Results are cached in a tiered memory + Redis SWR cache. Only positive
("has runs") results are cached, so an environment with no runs is
always re-checked and its first run shows up immediately.
Follow-up to #4194 (v3 execution app + core-helper removal). The v3
(engine V1) is end-of-lifed and enforced off in prod, so this removes a
self-contained slice of the remaining dead v3 code while **keeping every
user-facing deprecation message** - a user still on v3 must still be
told to upgrade.
## Legacy dev websocket
`app/v3/handleWebsockets.server.ts` backs the `/ws` transport used
**only** by the legacy v3 `trigger dev` CLI (v4 dev uses a different
transport). It's now authenticate-then-close with
`V3_DEV_DEPRECATION_MESSAGE`, so an old CLI is still told what to do -
only the legacy `AuthenticatedSocketConnection` / `DevQueueConsumer`
execution behind it (which can no longer run) is removed.
- Deleted `app/v3/authenticatedSocketConnection.server.ts` (its only
consumer).
- `engineDeprecation.server.ts` and the deprecation message constants
are untouched.
## Docs
Deleted the intentionally-legacy "Docker (legacy)" self-hosting page
(`open-source-self-hosting.mdx`) and redirected
`/open-source-self-hosting` (+ the existing
`/v3/open-source-self-hosting` alias) to `/self-hosting/overview`;
repointed the two inbound links. The current `self-hosting/*` docs
already describe the v4 (single supervisor) setup.
## Deliberately out of scope
Despite the branch name, this PR does **not** touch MarQS or the
socket.io coordinator/provider namespaces. Investigation found MarQS is
entangled with **live v2** queue/metrics/concurrency/project-cleanup
code (`runQueue`, `queueSizeLimits`, `taskRunConcurrencyTracker`,
`EnvironmentQueuePresenter`, `registerProjectMetrics`, `deleteProject`),
so it needs a per-file reviewed pass, not a bulk delete. That remainder
stays on TRI-11883.

## Summary
4 improvements, 5 bug fixes.
## Improvements
- Add SDK and API client helpers for run bulk actions.
([#4105](https://github.com/triggerdotdev/trigger.dev/pull/4105))
- Large batch payloads now offload to object storage instead of riding
inline in the trigger request. `batchTrigger` and `batchTriggerAndWait`
(and the by-id and by-task variants) offload any per-item payload over
128KB before sending, the same way single `trigger` and `triggerAndWait`
already do, so a big batch no longer blows past the API body limit.
([#4165](https://github.com/triggerdotdev/trigger.dev/pull/4165))
- Removed internal helpers that were only used by the end-of-life v3
self-hosted compute providers.
([#4194](https://github.com/triggerdotdev/trigger.dev/pull/4194))
- Add an `onEvent` callback to `TriggerChatTransport` /
`useTriggerChatTransport` that emits typed lifecycle events for sends,
stream connects, first chunk, and turn completion. Send-success metrics,
time-to-first-token, and "sent but never answered" watchdogs become a
few lines of client code.
([#4187](https://github.com/triggerdotdev/trigger.dev/pull/4187))
```ts
onEvent: (event) => {
if (event.type === "message-sent") metrics.timing("chat.send_ms",
event.durationMs);
if (event.type === "first-chunk") metrics.timing("chat.ttft_ms",
event.sinceSendMs ?? 0);
},
```
## Bug fixes
- fix(cli): honor the MCP server's `--dev-only` flag
([#4199](https://github.com/triggerdotdev/trigger.dev/pull/4199))
- Fix chat turns that throw (for example from an `onTurnStart` hook)
leaking their message listener, which lost or duplicated messages sent
during later turns.
([#4176](https://github.com/triggerdotdev/trigger.dev/pull/4176))
- Fix `chat.agent` and `chat.createSession` permanently dropping user
messages when several arrived during a single turn: every buffered
message is now dispatched as its own turn instead of only the first.
([#4176](https://github.com/triggerdotdev/trigger.dev/pull/4176))
- Fix chat continuation runs replaying already-answered messages: turns
delivered while the run was suspended now advance the session.in resume
cursor, so a new run picks up exactly where the previous one left off.
([#4176](https://github.com/triggerdotdev/trigger.dev/pull/4176))
- Fix `chat.createSession` swallowing a message sent shortly after
stopping a turn: the turn's message listener now detaches when the
stream settles, so those messages run as the next turn.

## Summary
UI/layout/copy pass over the org **SSO & Directory Sync** settings page
(formerly "Identity & Access"). No logic, gates, flags, or data flow
changed — server-side auth (`manage:sso`), Enterprise entitlement,
action validation, and data loading are all untouched.
- Renamed the nav item, page title, and meta from "Identity & Access" to
"SSO & Directory Sync".
- Added a reusable `SettingsLayout` component system (container,
section, header, row, block, actions) modeled on `/account/security`,
and refactored the SSO page onto it (section titles, dividers, left
title/subtitle + right action rows).
- Tightened all UI copy: concise, active voice, consistent labels, no
em-dashes.
- `Select` primitive: additive `wrap`, `popoverClassName`, and
`placement` props (all default to prior behavior) so role options show a
bright title with a wrapping description, right-aligned popover, and no
horizontal overflow.
- Removed the external-link arrow icon from buttons that open a modal;
kept it only on genuinely external actions (Contact us, Open in new
tab).
- Polished the admin portal link dialog: smaller description, tighter
spacing, `ClipboardField` with a permanent copy button, removed the
redundant Copy link button, and a provider-aware Open label (e.g. "Open
in WorkOS") derived from the link host with a safe fallback.

https://github.com/user-attachments/assets/b33a4ce9-c1fa-45c9-bd3c-077cb6fc9473
## Test plan
- [ ] Non-Enterprise org: SSO page shows the upsell state
- [ ] Enterprise org, non-Owner without `manage:sso`: 403
- [ ] Enterprise Owner: verify domains, configure SSO, connect
directory, JIT/default/group role selects, and enforcement toggle all
work
- [ ] Role select popovers: bright title + wrapping description,
right-aligned, no horizontal scroll
- [ ] Admin portal dialog: copy button works, "Open in WorkOS" opens the
portal in a new tab

## What
Adds a new Example projects page: **ClickHouse chat agent** — a
`chat.agent()` that answers questions about your data by writing and
running SQL against ClickHouse Cloud via the official Node.js ClickHouse
client.
The page follows the existing example-project format (overview,
features, GitHub repo card, how-it-works with code excerpts, relevant
code links) and is registered in `docs.json` in alphabetical order.
## Note
The GitHub repo card links to
`triggerdotdev/examples/tree/main/clickhouse-chat-agent`, which lands in
a companion examples PR — merge that one first.

v3 (engine V1) is end-of-lifed and the v3 clusters are gone, so this
removes the dead v3 execution code from the monorepo. It's the first
pass of TRI-11824 - the webapp v3 code paths are deliberately left
untouched and gated for a follow-up.
## Apps
Deletes the three v3-only execution apps and their build wiring:
- `apps/coordinator`, `apps/kubernetes-provider`, `apps/docker-provider`
- `.github/workflows/publish-worker.yml` - it built only those three;
the v4 worker publish is a separate workflow
- Their references in `.changeset/config.json`, `.cursorignore`,
`CHANGESETS.md`, `CONTRIBUTING.md`, `.server-changes/README.md`
- `pnpm-lock.yaml` regenerated to prune the apps and their app-only
dependencies (`socket.io`, `@kubernetes/client-node`, `p-queue`,
`execa`, `prom-client`, `tinyexec`)
## Core
Removes the helpers in `@trigger.dev/core` that only those apps used -
`ProviderShell`, `SimpleLogger`, the `Exec`/process helpers,
`isExecaChildProcess`, `getTextBody`, and `testDockerCheckpoint`. Each
was verified to have no remaining consumers anywhere in the repo.
Kept the helpers still used elsewhere: `ExponentialBackoff` (warm-start
client), `HttpReply`/`getJsonBody` (serverOnly http server),
`SimpleStructuredLogger` (widely used), and
`ZodNamespace`/`ZodSocketConnection` (still referenced by legacy v3
webapp code, hence the follow-up pass).
The `./v3/apps` and `./v3/serverOnly` export subpaths remain - only dead
members were trimmed from their barrels, so no `package.json` exports
changed.
## Verification
`@trigger.dev/core` builds, and `typecheck` passes for core, supervisor,
cli-v3, run-engine, redis-worker, and webapp.

### Problem
The agent playground chat builds its realtime transport baseURL from
apiOrigin, but points it at a same-origin /resources/... dashboard
route. When API_ORIGIN differs from APP_ORIGIN, the in/append POST goes
cross-origin, fails the CORS preflight, and messages never reach the
agent ("Failed to fetch").
It only reproduces where the two origins differ — not locally, where
both default to localhost:3030.
Fixes#4149.
### Fix
Build the base URL from window.location.origin (falling back to
apiOrigin on SSR), so realtime traffic stays same-origin — the same
approach AgentView.tsx already uses.
### Testing
Typecheck passes. The CORS path only manifests when API_ORIGIN !=
APP_ORIGIN, so verify on test-cloud (can't reproduce locally).
