fix(messaging): publishToAi 시 traceId MDC 누락 시 새 UUID 자동 생성#39
Merged
Conversation
운영 검증 중 발견. callback handler 흐름에서 자동 발화된 SessionEndedEvent →
SessionFeedbackRequester.publishToAi 호출 시 MDC 에 traceId 가 없어 envelope.traceId=null
로 발행. AI 측 Envelope[T] 의 traceId 가 string required 라 Pydantic ValidationError
('Input should be a valid string [...] input_value=None') 로 메시지 거절.
해결: publishToAi 내부에 fallback — MDC traceId null/blank 면 UUID.randomUUID() 채움.
JwtAuthenticationFilter 흐름은 MDC 가 채워져 있고, RabbitListener/TransactionalEventListener
흐름은 이 fallback 으로 균일하게 traceId 보장.
증상: 운영 골든패스 (Sprint3 verify, sessionId=4) 에서
- SessionFeedbackRequester: generate.feedback published. (정상)
- feedback consumer: feedback.parse.failed traceId: Input should be a valid string
- /api/sessions/4/feedback 무한 FEEDBACK_NOT_READY
