How to fix "azure.core.exceptions.ClientAuthenticationError: (None) Unauthorized. Access token is missing, invalid, audience is incorrect (https://cognitiveservices.azure.com), or have expired" during RAG creation tutorial?

I am trying to follow the steps of the tutorial: https://learn.microsoft.com/en-us/azure/ai-studio/tutorials/copilot-sdk-build-rag

I keep getting the error:

azure.core.exceptions.ClientAuthenticationError: (None) Unauthorized. Access token is missing, invalid, audience is incorrect (https://cognitiveservices.azure.com), or have expired.

Code: None

Message: Unauthorized. Access token is missing, invalid, audience is incorrect (https://cognitiveservices.azure.com), or have expired

I've triple checked my .env file to make sure everything is correct. The code is a direct copy of what is in the tutorial and I've double checked that everything is in the same region. I've tried re-logging into the CLI to make sure it's not that too. The code doesn't specify an api key, which I'm thinking maybe that's what it needs?

Hi Rebecca Molnar,
Greetings & Welcome to Microsoft Q&A forum! Thanks for posting your query!
It sounds like you're encountering an authentication issue. Here are some troubleshooting steps to resolve the issue:

Ensure that your access token is correctly set, not expired.

You can generate a new token using the Azure CLI. Re-logging into the Azure CLI can often resolve authentication issues, and it is also essential to check the token's expiry and refresh it if necessary.

Verify that the Azure region of your endpoint matches the region of your resources, as inconsistencies can cause authentication failures.

If the issue persists, consider explicitly passing the API key directly in the code when initializing the OpenAI client, as this simplifies authentication and avoids potential token-related errors.

Lastly, ensure that you are using the latest version of the Azure SDKs by running pip install --upgrade azure-ai-openai azure-identity.

I hope this information helps.

Hi,

Thanks for your response. As I mentioned before, I have checked all tokens, re-logged in multiple times, and triple checked the regions before making the question.

When I tried to run the pip install command, I get this error:

ERROR: Could not find a version that satisfies the requirement azure-ai-openai (from versions: none)

ERROR: No matching distribution found for azure-ai-openai
