## What
`dev` and `deploy` now fail with a clear error when two tasks are
defined with the same id — including across task types (e.g. a scheduled
task and a regular task sharing an id).
## Why
Tasks are registered into the resource catalog keyed by id, so a second
definition with the same id silently overwrote the first. One of the
tasks would just vanish from the worker with no warning — easy to miss,
hard to debug. (Any earlier duplicate-id check ran against the
post-registration task list, which is already de-duplicated, so it never
actually fired.)
## How
- **Detect at registration** (`@trigger.dev/core`):
`StandardResourceCatalog` records a collision when a task id is
registered more than once, capturing the files involved — the only point
where both definitions are visible before the id-keyed map collapses
them. Exposed via `listTaskIdCollisions()`.
- **Fail indexing** (`trigger.dev` CLI): both index workers report
collisions via a new `TASKS_FAILED_TO_INDEX` message;
`indexWorkerManifest` rejects with a new `DuplicateTaskIdsError`. `dev`
renders a dedicated error (offending ids + files + docs link); `deploy`
fails with the same message. Runtime worker boot is unaffected — it
never reads the collisions.
- **Server-side backstop** (webapp): background-worker registration also
rejects duplicate ids with a clear `ServiceValidationError`, so
duplicates are caught even from an older CLI.
## Testing
- Unit tests for collision collection in the catalog and for the
error-message formatting (standard, same-file, and 3+-definition cases).
- Verified end to end against a local webapp: a project with a regular
task and a scheduled task sharing an id now fails `dev` with the
dedicated error; a project with distinct ids still starts normally.
## Changeset
Patch for `@trigger.dev/core` and `trigger.dev`.

Adds backward-compatible support for large trigger payloads by reusing
the existing object-storage packet flow.
Large payloads are uploaded to object storage before the trigger request
is sent. The trigger API receives a small application/store pointer
payload instead of embedding large JSON bodies in the request.
Small payload behavior is unchanged.
On warm-started workers with `processKeepAlive` enabled, every run's
attempt span was exported with the first run's `traceId` and
`parentSpanId`. `ExternalSpanExporterWrapper` and
`ExternalLogRecordExporterWrapper` captured `externalTraceContext` at
`TracingSDK` construction, and the SDK is memoized for the worker's
lifetime - so the per-run reset of
`StandardTraceContextManager.traceContext` never reached the wrappers.
Reported by a customer running v4.4.x: 33 distinct runs on the same
host/pid showed up in their APM as siblings of one parent span.
Fix: the wrappers now read external context live from the trace context
manager per export. Runs without an external trace context fall through
to the unchanged `externalTraceId` fallback - no behaviour change for
them.
Regression test in
`packages/core/test/externalSpanExporterWrapper.test.ts` asserts that
reassigning the manager between exports produces correctly-parented
spans.
Retries `TASK_MIDDLEWARE_ERROR` under the task's retry policy.
`shouldRetryError` already classed it as retryable, but
`shouldLookupRetrySettings` did not, so the run fell through to
`fail_run` on attempt 1 instead of using the task's `retry` config.
Fixes#3231.
On a warm worker process, a task whose `task()` definition is loaded via
`await import(...)` from inside another task's `run()` could end up
permanently missing from the catalog: the `task()` call fired with no
`_currentFileContext` set, `registerTaskMetadata` silently returned, and
Node's ESM module cache then blocked the worker's setContext + re-import
recovery from ever firing the call again. Subsequent runs of that task
on the same warm process failed with `COULD_NOT_FIND_EXECUTOR` until the
process hit `maxExecutionsPerProcess` and exited.
All five of these had to coincide on the same worker for the bug to
surface:
1. `processKeepAlive` enabled (so catalog state survives across runs).
2. A `run()` function (or lifecycle hook) does `await import(...)`.
3. The import's transitive static graph reaches a `task()` /
`schemaTask()` call.
4. The task containing the dynamic import is the **first** task to run
on a given warm worker process — so the dropped `task()` calls fire on
this process for the first time, are silently dropped, and Node's module
cache locks the wrong outcome in.
5. A subsequent run for one of the dropped task ids lands on the same
warm worker before it recycles.
The runtime workers now set a sentinel file context (`<no-context>`)
around the `executor.execute(...)` call, so `task()` invocations firing
during a run register normally. The catalog detects the sentinel and
emits a one-time `console.warn` per task id so the pattern stays visible
without spamming. The indexer never sets this context, so deploy-time
behavior is unchanged.
Repro is `references/hello-world/src/trigger/dynamicImportRepro*.ts`.
Verified end-to-end against a deployed image with firestarter
warm-starts on: pre-fix saw `COULD_NOT_FIND_EXECUTOR` on children that
landed on the parent-poisoned worker; post-fix all 23/23 runs succeeded
and the warning surfaces in the parent's run trace.
Adds the chat.agent({...}) task definition (server runtime) and the
browser-side TriggerChatTransport + AgentChat that drives it from a
React or Next.js app. The runtime sits on top of the Sessions primitive
and handles the durable conversational task lifecycle.
Server runtime:
- chat.agent({...}) — session-aware task definition
- Lifecycle hooks: onChatStart, onTurnStart, onTurnComplete, onAction,
onValidateMessages, hydrateMessages
- chat.history read primitives for HITL flows
- chat.local, chat.headStart, chat.handover, oomMachine
- Delta-only wire + S3 snapshot reconstruction at run boot
- Actions are no longer turns
Browser transport:
- TriggerChatTransport (ai-sdk Transport): delta-only wire sends,
SSE reconnection with lastEventId resume, stop/abort cleanup,
dynamic accessToken refresh
- AgentChat: direct programmatic API
- useTriggerChatTransport (React hook)
- chat-tab-coordinator: cross-tab leader election
Includes the chat-agent, chat-agent-delta-wire-snapshots,
chat-history-read-primitives, chat-head-start, chat-actions-no-turn,
chat-session-attributes, agent-skills, and mock-chat-agent-test-harness
changesets.
Adds Sessions, a durable, run-aware stream primitive that scopes
session.in / session.out records to a session (not a single run).
Records survive run boundaries; reconnect-from-last-event-id is built in.
Server foundation:
- New /realtime/v1/sessions/:session/:io/append + /records routes
- sessionRunManager + sessionsRepository + clickhouseSessionsRepository
- mintRunToken for short-lived per-session tokens
- s2Append retry-with-backoff + undici cause diagnostics
- /api/v[12]/packets/* exempt from customer rate limits
- BackgroundWorker schema gains taskKind enum (TASK, AGENT, SCHEDULED)
- TaskRun.taskKind column + clickhouse 029_add_task_kind_to_task_runs_v2
Core types:
- new sessionStreams, inputStreams, realtimeStreams packages in @trigger.dev/core
- session-streams-api / realtime-streams-api surface
Sessions dashboard UI (the primitive's own viewer):
- /sessions index + detail routes
- SessionsTable, SessionFilters, SessionStatus, CloseSessionDialog
- AGENT/SCHEDULED filter in RunFilters + TaskTriggerSource
Includes the sessions-primitive changeset.
Closes
[TRI-9234](https://linear.app/triggerdotdev/issue/TRI-9234/retry-task-process-sigsegv-errors-respecting-user-retry-config)
## What this changes
SIGSEGV crashes (`TASK_PROCESS_SIGSEGV`) will now be **retried when an
attempt fails**, in line with the task's configured retry settings
(`retry.maxAttempts` etc.) — the same path SIGTERM and uncaught
exceptions already use. Previously SIGSEGV was hard-classified as
non-retriable and failed the run on the first segfault, ignoring the
user's retry policy.
Tasks without a retry policy still fail fast on the first SIGSEGV.
Behaviour is unchanged for OOM kills (separate machine-bump retry path)
and SIGKILL_TIMEOUT.
## Deploy
**Only the webapp needs to ship.** The retry decision lives entirely in
the webapp:
- V2 path: `internal-packages/run-engine` (bundled into the webapp)
- V1 path: `apps/webapp/app/v3/services/completeAttempt.server.ts`
No supervisor, CLI, SDK, or customer-task-image changes required.
Customers do not need to redeploy. The `@trigger.dev/core` changeset is
just keeping the public package in sync — the published npm version
isn't what makes the fix work.
## Why retry
SIGSEGV in Node tasks is frequently non-deterministic across processes:
- **Native addon races** (`sharp`, `canvas`, `better-sqlite3`,
`node-rdkafka`, `bcrypt`, …) — libuv thread-pool work stepping on V8
handles. Different heap layout / thread schedule on a fresh process →
retry often succeeds.
- **JIT / GC interaction** — V8 turbofan deopt or GC during a native
callback. Timing-dependent.
- **Near-OOM in native code** — when RSS approaches the cgroup limit,
native allocations fail and poorly-written addons dereference NULL →
SIGSEGV instead of clean OOM-kill.
- **Host / hardware issues** — bit flips, kernel quirks. Retry lands on
a different host.
The genuinely deterministic case (a user-code bug always tripping the
same addon) is real, but a subset — and `maxAttempts` bounds the damage.
## Pre-existing inconsistency this resolves
- `shouldRetryError` returned `false` for `TASK_PROCESS_SIGSEGV` →
`fail_run`.
- `shouldLookupRetrySettings` already listed `TASK_PROCESS_SIGSEGV` as
retry-config-aware — but that branch was unreachable because
`shouldRetryError` short-circuited first in `retrying.ts:86-90`.
- We already retry `TASK_RUN_UNCAUGHT_EXCEPTION` (clearly a user-code
bug) under the user's retry policy; refusing to retry SIGSEGV was the
odd one out.
## Test plan
- [x] `pnpm exec vitest run test/errors.test.ts` in `packages/core` —
26/26 pass (4 new)

## Summary
Large error stacks and messages can OOM the worker process when
serialized into OTel spans or `TaskRunError` objects. This was reported
when throwing an error with a massive `.stack` property from a chat
agent hook.
This adds frame-based stack truncation (similar to Sentry's approach)
plus message length limits, applied consistently across all error
serialization paths.
### What changed
**`packages/core/src/v3/errors.ts`**
- `truncateStack()` — parses `error.stack` into message lines + frame
lines, caps at 50 frames (keep top 5 closest to throw + bottom 45 entry
points, with "... N frames omitted ..." in between). Individual lines
capped at 1024 chars.
- `truncateMessage()` — caps error messages at 1000 chars
- Applied in `parseError()` and `sanitizeError()`
**`packages/core/src/v3/otel/utils.ts`**
- `sanitizeSpanError()` now uses `truncateStack` and `truncateMessage`
from `errors.ts` instead of duplicating truncation logic
- Non-Error values (strings, JSON) capped at 5000 chars
**`packages/core/src/v3/tracer.ts`**
- `startActiveSpan` catch block now delegates to `recordSpanException()`
instead of calling `span.recordException()` directly
### Limits
| What | Limit | Rationale |
|------|-------|-----------|
| Stack frames | 50 | Matches Sentry's `STACKTRACE_FRAME_LIMIT` |
| Top frames kept | 5 | Closest to throw site |
| Bottom frames kept | 45 | Entry points / framework frames |
| Per-line length | 1024 | Matches Sentry, prevents regex DoS |
| Message length | 1000 | Bounded but generous |
| Generic string (non-Error) | 5000 | Fallback for JSON/string errors in
spans |
## Test plan
- [x] 17 unit tests in `packages/core/test/errors.test.ts`
- [x] E2E: threw a 300-frame / 5000-char-message error in the ai-chat
reference app, verified truncated stack and message in span via
`get_span_details`
- [x] Verified the run survived the error (no OOM, continued waiting for
next message)
## Summary
- Upgrades Node.js from 20.19.0 to 20.20.0 (and 22.12.0 to 22.22.0 for
supervisor) to address the async_hooks stack overflow DoS vulnerability
- Adds `maxDepth` parameter (default 128) to `flattenAttributes` and
`unflattenAttributes` to prevent stack overflow on maliciously deep
nested structures
## Details
The vulnerability (patched in Node.js 20.20.0, 22.22.0, 24.13.0, 25.3.0)
causes unrecoverable crashes (exit code 7) when stack overflow occurs
during async_hooks callbacks. Since the webapp uses `AsyncLocalStorage`,
it was theoretically vulnerable.
### Changes
**Node.js version updates:**
- `docker/Dockerfile`: 20.11.1 → 20.20.0
- `apps/supervisor/Containerfile`: 22-alpine → 22.22.0-alpine
- `.nvmrc`: 20.19.0 → 20.20.0
- `apps/supervisor/.nvmrc`: 22.12.0 → 22.22.0
- `references/prisma-7/.nvmrc`: 20.19.0 → 20.20.0
- All GitHub workflows: 20.19.0 → 20.20.0
**Defense in depth:**
- Added `maxDepth` parameter to `flattenAttributes()` and
`unflattenAttributes()` in `packages/core` to prevent stack overflow on
deeply nested user input
## Test plan
- [x] All existing `flattenAttributes` tests pass (50 tests)
- [x] New tests for depth limiting added
- [x] Verify Docker builds work with new base images
