Cause (Documented platform behavior): Node escalates unhandled "error" events and rejections to uncaughtException, which the runtime reports as TASK_RUN_UNCAUGHT_EXCEPTION.
Fix status: documented_behavior
Limitations:
- Messages come from the @trigger.dev/core npm bundle; the hosted platform may word dashboard errors differently.
