- After terraform destroy, we attempt to run terraform plan again but get the following errors:

```

- To fix this we had to use az cli to delete the rules from Azure, e.g:

```
az network firewall application-rule collection delete --collection-name ${targetCollection} --firewall-name ${targetFw} --resource-group ${targetRsg}
```

NOTE: The rules did not appear as duplicates in the terraform state.
