Employee Event Delivery Troubleshooting

Summary​

Domain-to-outbox mapping, Employee outbox processor boundary, shared publication, and confirmed consumers.

Audience​

  • HR administrators, support engineers, developers, QA engineers, and DevOps engineers

Symptoms​

An Employee change is persisted but not reflected in a documented downstream consumer.

Scope​

Domain-to-outbox mapping, Employee outbox processor boundary, shared publication, and confirmed consumers.

Cause​

Likely causes​

  • Operation did not raise the expected event
  • Outbox message is pending/failed
  • No Employee-hosted relay invocation is configured
  • Target event has no confirmed consumer
  • Consumer rejected, requeued, deduplicated, or treated the event as stale

Safe diagnostic steps​

  1. Confirm the event should exist in the catalog and the producer route is Employee Service
  2. Use approved safe outbox status/age evidence without reading payloads
  3. Confirm processor invocation and source-confirmed consumer support
  4. Check sanitized consumer acknowledgement/idempotency evidence

Resolution​

Safe resolution​

  • Escalate missing relay ownership or failed publication to Employee/messaging owners
  • Resolve consumer availability/contract issues through its owner
  • Replay only under approved governance after idempotency review

Validation​

A new synthetic change progresses through the expected source-confirmed stages without duplicate side effects.

Evidence to collect​

Event type/identifier, safe aggregate identifier, status/retry category, occurrence window, correlation identifier.

Escalation​

Employee owner for production/outbox; messaging owner for transport; consumer owner for downstream handling.
