Type Alias ErrorHookPayload

ErrorHookPayload:
    | WorkflowPayloadBase & { error: Error; source: "workflow" }
    | ActivityErrorHookPayload & { source: "activity" }
    | HookPayloadBase & { error: Error; source: "runtime" }

Payload passed to the onError() handler when a workflow, activity or runtime error occurs.

WorkflowPayloadBase & { error: Error; source: "workflow" }
- error: Error
  Workflow error rehydrated after crossing the Temporal sandbox boundary. Preserves name, message, cause, and other enumerable properties from the serialized form; it is a reconstructed Error, not the original class. Extra fields are present at runtime but not on the Error type — narrow or cast in TypeScript when you need them.
- source: "workflow"
  Workflow error origin.
ActivityErrorHookPayload & { source: "activity" }
- source: "activity"
  Activity error origin.
HookPayloadBase & { error: Error; source: "runtime" }
- error: Error
  The original error instance.
- source: "runtime"
  Worker runtime error origin.
