The generic webhooks.slack() SDK source was auto-generated from the core provider config, which carries only the HMAC verifier. Slack additionally needs the one-time url_verification handshake (before an Event Subscriptions URL can be saved) and form-encoded interactivity parsing, so an endpoint built from webhooks.slack() could never be connected. Drop slack from the generated SDK producers (runtime + type) and export webhookSource() from @trigger.dev/slack, which carries the handshake + formPayload the connector already uses. Users get a plain Slack webhook source from webhookSource(), or the full chat channel from slack(). Core's slack config stays for server-side verification.
