    Yes, there is a limitation. Fabric notebooks run inside a sandboxed env that does not support managed identity based auth to external azure services such as azure ML. DefaultAzureCredential will not work because the fabric runtime does not expose a MI, even if you grant permissions on the ML workspace. That is why the token retrieval fails.
