Cupix::Errors::BadGateway: {"result"=>{"code"=>"BG10004", "type"=>"Cupix::Errors::BadGateway", "reason"=>"Failed to fetc

What Happened#

Facility migration 요청 처리 중 migration-service(cupixworks monorepo)가 tesla API(GET /api/v1/facilities/{id})를 호출해 source/destination facility 정보를 가져오려다 tesla 가 401 Unauthorized 를 반환했다. migration-service 는 이 401 을 Cupix::Errors::BadGateway(code BG10004)로 감싸 502 로 응답하고 error 레벨 로그를 남긴다. 2025-11-28 부터 2026-07-28 까지 약 8개월간 51건이 산발적으로 발생했다.

APM service 필드는 cupixworks-api 로 기록되어 있으나, 에러 메시지("Failed to fetch facility info from tesla server")와 code BG10004 문자열은 tesla 가 아니라 tesla 를 호출하는 migration-service 에서 발생한 것이다.
