Hi @Zoe Zhou , The error AADSTS50019: No tenant-identifying information found in either the request or implied by any provided credentials is caused by the absence of tenant-identifying information in the request or credentials. To avoid this error, you can try the following actions:
- Ensure that you have specified the correct tenant ID in your request.
- Make sure that you have provided the correct credentials for the tenant.
