Missing Lambda function in eu-central-1 region — config mismatch

What Happened#

2026-05-22 03:22~04:30 UTC 사이에 eu-central-1 리전의 cupixworks-worker에서 UploadCpcLogWorker가 Lambda 함수 cupix-json-collector-dc96을 호출했으나, 실제 배포된 함수 이름은 cupix-json-collector-dcg6(Terraform-managed, 2026-05-13에 마지막 수정)이라 ResourceNotFoundException이 발생했다. 9와 g가 한 글자 차이로 오탈자가 발생한 config typo다. 동일 시간대 다른 리전(us-west-2, ap-southeast-2)의 동일 worker는 정상 동작했다.
