[CupixAerialMap] postprocess fail - error:({"message":"VipsJpeg: Corrupt JPEG data: premature end of

What Happened#

2026-07-22 00:03:35 KST 에 production aerial-map-service (us-west-2) 의 postprocess Fargate 태스크가 VipsJpeg: Corrupt JPEG data: premature end of data segment 예외로 종료되었다. Aerial map id 546 (session 11381160) 한 건의 processing pipeline 이 실패했고, ECS task 는 exit code 1 로 stop, Step Functions 는 States.TaskFailed 로 전이했다. 동일 postprocess 실행에서 catch 두 지점이 각각 로그를 남겨 fingerprint 가 다른 두 cluster (41be567a-…, d913e019-…) 로 잡혔다.
