Test Run Issue with No Authentication - AuthenticationNotConfigured

[SiddharthPoweCat]

I configured the agent with the “No Authentication” option enabled.
The Token Endpoint from the Direct Line Speech channel was added to the Agent Configuration, and Channel Security is turned off.
Although my test runs complete successfully, I encounter the following error message:
Sorry, the bot can't talk for a while. It's something the bot's owner needs to address.
Error code: AuthenticationNotConfigured.

The Copilot agent uses a Dataverse table as a knowledge source, and I see the same error when testing the agent within the Copilot Studio test pane while the “No Authentication” option is selected.

Problem Summary:

When configuring a Copilot agent with the “No Authentication” option, setting the Token Endpoint, and turning Channel Security off, you encounter the error: AuthenticationNotConfigured. This occurs specifically when Dataverse is used as the knowledge source.

Step-by-Step Solution:

1. Switch to Manual Authentication:
   • Change the agent's authentication setting from “No Authentication” to “Manual Authentication.”
   • Follow the steps in the ENABLE-AUTHENTICATION.md documentation to configure authentication for Dataverse access.
   • Use the token endpoint from Channels → Email (not Direct Line Speech).
   • Ensure channel security settings are properly configured.
2. Alternative Approach:
   • If you do not want to configure authentication, use a knowledge source other than Dataverse (such as SharePoint or websites), which may support “No Authentication.”

Additional Context:

• This is a known platform limitation and not a misconfiguration.
• Users have resolved this by switching to Manual Authentication and configuring the required settings for Dataverse access.
