Elasticsearch::Transport::Transport::Errors::NotFound: [404] {"error":{"root_cause":[{"type":"document_missing_exception

What Happened#

tesla (cupixworks-api / cupixworks-worker)의 Searchable concern이 레코드 update 시점에 Elasticsearch _update 요청을 보내는데, 대상 문서가 아직 색인되지 않은 상태라 ES가 [404] document_missing_exception을 반환한다. 이 실패한 client.update HTTP 요청이 cupixworks-elasticsearch APM instrumentation span에 error로 태깅되어 Error Tracking 이슈로 집계된다. 다만 애플리케이션 코드는 이 예외를 명시적으로 rescue 하여 warn 로그를 남기고 _index_document로 문서를 재색인하므로, 사용자에게 노출되는 실패나 데이터 유실은 없다.
