ActiveModel::MissingAttributeError: missing attribute 'origin_x' for Building

What Happened#

2026-08-06 롤링 배포 진행 중(production, us-west-2) GET /api/v1/buildings/{id} (Api::V1::BuildingsController#show) 요청이 약 30분 동안 HTTP 500 을 반환했다. BuildingSerializer 가 record.origin_x 를 읽는 순간, 해당 요청을 처리한 일부 앱 인스턴스의 Building 모델이 origin_x 컬럼을 인식하지 못해 ActiveModel::MissingAttributeError 또는 NoMethodError 가 발생했다. 배포가 끝난 뒤(14:42 KST 이후) 에러는 저절로 사라졌고 #index 요청은 정상 200 을 반환했다.

Timeline#

  1. 2026-08-06 14:11 KST — GET /api/v1/buildings/59 부터 500 급증 시작 (배포 창 진입)
  2. 2026-08-06 14:11–14:42 KST — buildings 48/58/59 에 대해 MissingAttributeError 와 NoMethodError 가 번갈아 발생 (ET first_seen 05:11:51Z ~ last_seen 05:42:15Z UTC)
  3. 2026-08-06 14:42 KST — 마지막 500 발생 (GET /api/v1/buildings/48)
