- Fix worker crash on compile error (eek!)
- on compile error, use step name in output
- on lazy state error, return a position and better messaging
…ng (#1311) * fix(ws-worker): remove async promise antipattern in run-log.ts The non-batch log path wrapped an async function in `new Promise(async (resolve) => { ... })`. If sendEvent rejected (e.g. channel timeout), the outer Promise never settled and the rejection was unhandled. This was the direct cause of the worker crash: LightningTimeoutError on run:log became an uncaught exception that killed the container. The function is already async so the wrapper was unnecessary — replaced with a plain for-loop that properly propagates rejections. * fix(ws-worker): remove async promise antipattern in try-with-backoff.ts Same `new Promise(async ...)` antipattern as run-log.ts. If the isCancelled callback or any other code in the catch block threw, the error became an unhandled rejection instead of propagating to the caller. Replaced with an inner async function that returns its promise directly. setTimeout retry replaced with awaited promise to keep the flow async-native. * fix(ws-worker): remove async promise antipattern in destroy.ts Same `new Promise(async (resolve) => { ... })` pattern — if engine.destroy() or waitForRunsAndClaims rejected, the outer promise never settled. Replaced with an async IIFE so errors propagate through Promise.all to the caller. * fix(engine-multi): emit compilation log before workflow-error During a compilation failure, engine-multi emitted WORKFLOW_ERROR (from the worker:error handler) before the "Error occurred during compilation" WORKFLOW_LOG (from the .catch handler). The ws-worker tears down the channel on WORKFLOW_ERROR, so the subsequent log push had nowhere to go — triggering the LightningTimeoutError that crashed the container. Moved the compilation log into the worker:error handler so it emits before the error event. Guarded the .catch handler's log with !didError to avoid duplication. Added COMPILE_START/COMPLETE events to mock-run.ts to match real worker behavior. * chore: add changesets for worker crash fixes * chore: exclude engine-multi tmp from pnpm workspace Test fixture directories under packages/engine-multi/tmp/ were being picked up as workspace packages by the packages/** glob, pulling in phantom dependencies (ava@6.x and its full transitive tree) that caused persistent lockfile churn. * remove duplicate log, tidy types * update changelogs * tidy test * revert diff on destroy * keep destroy change after all and fix test * relax runtime test it just went flaky --------- Co-authored-by: Joe Clark <jclark@openfn.org>
* engine: report compile errors with step name, not id * changeset * remove debug code
* compiler: improve error messages for lazy state * compiler: report position on lazy state reporting * update extra errors * update changeset * types
