# X_JOB_CLAIM_QUEUES_EMPTY

## Means

a driver was asked to claim with `queues: []`

## Typical cause

an empty list names no queue, and the two shipped drivers had two meanings for it — every queue on the memory driver, the `default` queue on the Postgres one — while `ClaimOptions.queues` documented neither. Each meaning is silently wrong in the other's deployment: one takes work this worker was never configured for, the other drains nothing and reads as an idle queue. Reachable only by an embedder, since `jobWorker` passes exactly one queue per pass

## Fix

pass the queue by name — `driver.claim({ queues: ['default'], limit, visibilityTimeoutMs, workerId })` — or read the list from `jobs.queues`, which is what `jobWorker` walks one queue at a time
