Failed to create event: Mysql2::Error: Data too long for column 'sys' at row 1

What Happened#

PUT /api/v1/facilities/t7v38v/share 요청이 권한 적용까지는 성공한 뒤, share event를 기록하기 위해 Event 레코드를 저장하는 단계에서 events.sys 컬럼에 들어갈 직렬화된 JSON이 TEXT 한계를 초과해 ActiveRecord::ValueTooLong으로 거절되었다. 클라이언트에는 400이 응답되었고, share event 생성과 이후 알림 워커 트리거가 누락되었다.

Quick Facts#

Field Value
exception.class ActiveRecord::ValueTooLong (root: Mysql2::Error)
exception.message Mysql2::Error: Data too long for column 'sys' at row 1
top_frame app/models/concerns/eventable/events/base.rb:20 (rescue/log site)
failure_origin app/factories/event_factory.rb:102 (self.model.save)
endpoint PUT /api/v1/facilities/:key/share (Api::V1::FacilitiesController#share)
env production, region us-west-2, tenant cupix
