Databricks App OAuth token request failed with status {exc.r

Error message

Databricks App OAuth token request failed with status {exc.response.status_code}

What it means

The Databricks App OAuth token endpoint returned an HTTP error status during the client-credentials grant. Converted to ValueError so the agent call fails with a clear auth-acquisition message including the status code.
