Azure ML 2.38 fails to create models

### Describe the bug

The release of 2.38 of the azure ml library fails to create models

The new version is causing the command `az ml model create` to fail

No other code has changed within these pipelines and repos over the last week

### Related command

As part of our setup for azure ML pipelines we install the latest release version
```cmd
az extension add -n ml -y --allow-preview false
```

Todays logs add the following, which was not present the previous day
```

### Errors
