How it arrives

{
  "type": "https://docs.tempinbox.vn/errors/validation.failed",
  "title": "…",
  "status": 422,
  "code": "validation.failed",
  "traceId": "…"
}

Match on code, never on title — titles are prose and may be reworded. Quote traceId when asking for help; it follows the request across every service.
