Hi,

How are you? I hope this post finds you all well.

I have a azure resource and qnamaker.ai knowledge base that I am trying to pass back through power virtual agents for teams.

The flow looks like this:

But when I run the flow, I get the following error:

{

"statusCode": 401,

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

}

I have added the API key to the connection prior to this step and that screenshot looks like this:

The API coming from the Cognitive Services part of Azure under keys and endpoints.

All the info from the generate answer action is coming from the qnamaker website:

Thanks in advance

I have a feeling the problem is I am not being shown the Endpoint key but the Ocp-Apim-Subscription-Key.

Where do I find the endpoint key ?

In this website

There is this part, and the APIM key is not shown, the endpoint key is shown:

Hi @Jondoesflow,

Your setup looks ok. The EndPoint key can be found in the deployment details section of the website.

Just to double check. What is the location of your QnA service. Is it westus or something else?

I believe the connector defaults to westus when you leave the site url empty:

Hi @Jondoesflow,

Yes, I would try and change it. To see if that makes a difference.

Can you set the Site Url of the connection of your QnA maker action to this value: https://northeurope.api.cognitive.microsoft.com

The deployment details can be found on the QnA Maker website.

1. Go to https://www.qnamaker.ai/Home/MyServices

2. Edit your target Kb, there should be a settings button in the right top corner

3. On the settings it should be listed at the bottom of the page

Facing the same error with the new "custom question answering".

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

For QnA connection, used the Key1 and EndPoint from the Cognitive Service in Azure. EndPoint is "https://textanalytics-customquestoinanswering.cognitiveservices.azure.com"

Hi @leiwang,

I believe @Jondoesflow had this issue because his QnAMaker was using the new Managed feature, correct?
