X_JOB_NOT_REQUEUEABLE
Means
the job is still live and cannot be requeued
Typical cause
x jobs retry / requeue was asked for a job that is ready, delayed or running. Requeueing a running job left claimed_by set with state ready, so a second worker claimed it and it ran twice. Only a dead, cancelled or done job may be requeued
Fix
x jobs cancel <id> first, then x jobs retry <id>
