Description

When calling the service_principals.get() with a valid service principal id the request failed with the following error

Traceback (most recent call last):

databricks.sdk.errors.platform.PermissionDenied: unable to parse response. This is likely a bug in the Databricks SDK for Python or the underlying API. Please report this issue with the following debugging information to the SDK issue tracker at https://github.com/databricks/databricks-sdk-go/issues.

Reproduction
A minimal code sample demonstrating the bug.

import json
from databricks.sdk import WorkspaceClient

def main():
    host = "<<databricks host>>"
    token = "<<token>>"
    client = WorkspaceClient(host=host, token=token)

    id = client.service_principals.list()[0].id
   details = client.service_principals.get(id)
   print(json.dumps(details.as_dict()))

if __name__ == "__main__":
    main()

Expected behavior

1. The failure "unable to parse response" should not have occurred
2. The url pointed by the error message should point to this library and not the golang version of the same

Is it a regression?
Did this work in a previous version of the SDK? If so, which versions did you try?
No

Other Information

• OS: Mac OS
• Library Version: 0.32.2

2. The url pointed by the error message should point to this library and not the golang version of the same

Have fixed the above expected behavior in PR #767
