failed to merge voxels - error: 500 Internal Server Error

What Happened#

2026-04-28 00:34~00:48 UTC 사이에 cupixworks-api 서비스의 Cupix::VoxelService.merge_voxel 메서드에서 downstream voxel-service Lambda (nswgov-production-voxel-merge)로의 HTTP 호출이 500 Internal Server Error로 23회 실패했다. 원인은 Lambda 내부의 Athena SQL 쿼리에서 voxel 좌표값(x, y)을 CAST(... AS INTEGER)로 변환할 때 값이 32-bit 정수 범위(±2.1B)를 초과하여 NUMERIC_VALUE_OUT_OF_RANGE 오류가 발생한 것이다. nswgov 테넌트의 ap-southeast-2 리전에서만 발생했다.
