PLAY RECAP *******************************************************************************************************************************

```

Start with google/cloud/plugins/modules/gcp_compute_address.py and the gcp_utils.py traceback, then reproduce the failure from test_sql_playbook.yml at line 168 using the provided playbook task. Check how the module handles the VPC_PEERING purpose with a subnetwork; done means the task creates the requested address without the GCP invalid-purpose error.
