Microsoft.Agents.AI.Purview - No listeners are available to process the job.

[manfuj]

Hi, apologies if this is not the right channel for asking this question.

We're attempting to use the Purview SDK integration in the Agent Framework but we're hitting an error that we don't know how to navigate and we couldn't find any guidance online.

We've configured an application in Entra with the specified delegated permissions, approved by an administrator. Debugging shows that the framework is obtaining the token ok for an user via the InteractiveBrowserCredential. We are using dotnet 8.0.

However, the ChannelHandler is throwing an exception for "No listeners are available to process the job." on line 50. We've checked the MaxConcurrentJobConsumers setting and it does maintain its default value of 10. Setting the flag to ignore the exception results into an "Unknown method" exception thrown downstream.

We're not sure what we're doing wrong, if this is an issue with the code configuration, with the Entra configuration, or with the Purview configuration.

Just a shot in the dark with this message but any help and/or guidance would be very much appreciated.

For those encountering the same error, we have fixed the "No listeners are available to process the job." Purview exception by ensuring that the Purview policies are scoped to the Entra Client Id via PowerShell. We had previously configured the policies via the Purview UI but that was not sufficient.

Closing this now, it was a user error.
