failed to merge voxels - error: Timed out reading data from server
What Happened#
2026-08-07 07:22 KST 에 production cupixworks-api 에서 GET /api/v1/levels/47975/voxels (voxel viewer 의 merged-voxels 다운로드) 요청 1건이 HTTP 500 으로 실패했다. tesla 가 downstream voxel-service 의 /merge Lambda 를 호출했으나 Lambda 가 30 s 안에 응답을 시작하지 못해 RestClient::Exceptions::ReadTimeout (Timed out reading data from server) 이 발생했고, Cupix::VoxelService.merge_voxel 이 이를 Cupix::Errors::System (SYS20000) 으로 변환해 사용자에게 500 을 반환했다. downstream Athena 쿼리 지연에 의한 transient 실패이며 tesla 코드 결함이 아니다.
