InvalidParameterException on task_id: arn:aws:ecs:us-west-2:619071347432:task/cupix-tesla-ece/48ecc8
What Happened#
2026-07-01 11:55 KST부터 cupixvista-api-worker(tesla repo, LAUNCH_MODE=CUPIXVISTA)에서 ECS task 48ecc8fc146c40e6b7f1da84a352577b에 대해 AwsTask#stop!을 호출할 때마다 InvalidParameterException: The referenced task was not found가 발생하고 있다. 해당 task 자체는 2026-07-01 10:45:32 KST에 이미 ECS 상에서 STOPPED 상태가 되었고, 이후 ECS retention window(약 1시간)가 만료되면서 describe/stop 대상에서 사라졌다. 그럼에도 Cupix::Cron::Job.clean_running_jobs 크론이 10분마다 같은 task를 반복적으로 stop 시도하고 있다.
