[ISSUE] serving_endpoints.query raises BadRequest error when using azure-client-secret auth

[ericfeunekes]

Description
When using azure-client-secret auth, trying to query a model serving endpoint creates the following error (I replaced the actual UUID with :

databricks.sdk.errors.platform.BadRequest: io.jsonwebtoken.IncorrectClaimException: Expected aud claim to be: , but was: <UUID>.

Reproduction

1. Use azure-client-secret auth to instantiate a WorkpspaceClient
2. use w.serving_endpoints.query
3. Error is raised

Expected behavior
Bad Request error should not be raise

Is it a regression?
Don't know

Debug Logs
anything in angle braces is something I replaced for privacy

Other Information

• sdk version: 0.28.0

Additional context
The SPN has query permission on the endpoint. When I test the exact same endpoint/query with my own PAT, with the same permissions, it works. Also, when I use the same SPN to query a table using the same version of the SDK it works.
