failed to retrieve allocation bucket: %v

Error message

failed to retrieve allocation bucket: %v

What it means

putTaskRunnerLocalStateImpl calls getTaskBucket to obtain/create the per-task bucket inside the alloc bucket; this error is returned when the bucket cannot be fetched or created, so persisting TaskRunner LocalState fails and the write transaction aborts.

Solutions

1. Check that the alloc bucket exists (state not wiped mid-run)
2. Inspect DB health/permissions on the client state dir
3. Retry after transient bolt errors; recreate state via alloc re-adoption
