job %q is in nonexistent node pool %q

Error message

job %q is in nonexistent node pool %q

What it means

upsertJobImpl refused to register the job because the job's node pool does not exist in the state store; after defaulting an empty pool to `default`, the referenced pool must already be created.

Solutions

1. Create the node pool first (`nomad node pool apply`)
2. Set the job's node_pool to an existing pool such as `default`
3. Check for typos in the node pool name
