Class: UnhandledRejectionError

worker.UnhandledRejectionError

Thrown from the Workflow Worker when a Promise is rejected, but there is no catch handler for that Promise. This error wraps the original error that was thrown from the Promise.

Occurrence of this error generally indicate a missing await statement on a call that return a Promise. To silent rejections on a specific Promise, use promise.catch(funcThatCantThrow) (e.g. promise.catch(() => void 0) or promise.catch((e) => logger.error(e))).
