```

### Expected behavior

It should produce a json output that lists the various VM skus and their capacities/capabilities

### Environment Summary

```
azure-cli 2.57.0

core 2.57.0
telemetry 1.1.0
```

### Additional context

I tried rolling back to older Azure CLI 0.55 and it too fails in the same way.
