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.
