# X_DEPLOY_QUEUE_UNSERVED

## Means

a registered queue has no serving worker of this build

## Typical cause

no worker row that is not draining and runs this build claims the queue

## Fix

`x jobs list --json   # then WORKER_QUEUES=<queue> on a worker Deployment, or --idle-ok <queue> on the deploy verify subcommand for a scale-to-zero pool`
