Question

Deployed a model and in the chat playground is working ok, but when deployed into the webapp it gives me this error: AuthenticationError: Error code: 401 - {'error': {'code': 'PermissionDenied', 'message': 'Principal does not have access to API/Operation.'}} Any guidance will be a great help

@Orlando Herrera Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

Please follow the below action plans:

• assign the RBAC role Cognitive Services Contributor and Cognitive Services OpenAI User to the user (Service principal) from Azure portal for your Azure Open AI resource.
• Enable the managed identity for your webapp and then give the same above RBAC permission on Azure OpenAI resource.
• Then test this from your application and check if that helps.

Awaiting your reply.
