I have built an agent without any topics mostly driven through Instructions I have a knowledge source (sharepoint) attached to it, By default All knowledge sources that are added at the agent level are added to generative answers node in the Conversational boosting system topic according to the documentation, but it is not the case and I don't a response from the agent and is stuck at the response generation phase.

    Can you show some screenshots to see how you’ve configured the knowledge source?
    you shouldn’t have to touch anything in the Conversational boosting topic.
     
    Also show how you’ve configured the authentication settings in the security section.

    The user you’re running the agent with, must have access to the Sharepoint data source you’re trying to use from the agent

    So the knowledge source is connected to a sharepoint library and the status is 'Ready'(using the sharepoint connector from knowledge sources tab - not the one near upload files), it's a blank agent with no user defined topics. when the user asks a query it triggers the 'Conversational boosting' system topic after disabling the system topics 'fallback' and 'multiple topics matched' once the 'Conversational boosting' topic is triggered it goes to the GA node inside the topic but doesn't provide any response.

    The user has access to sharepoint - I can confirm this because when i have created a user defined topic with a GA node in it I have got responses.

    So I have opened the GA node of the topic to check if the Knowledge source is added to the Node's knowledge source by default and No it didn't add it.
    So
    1.If it directly uses the Knowledge source without adding it to GA node - failed - no responses received.
    2. If it should add the GA Node as a knowledge source - Failed -not added.

    But GA Node is also acting wierd with user topics, It is just stuck at the generation forever(not all the time but few times - which is frustrating) also returns duplicate results in a markdown table as an output define in the prompt of the GA Node even when explicitly added to the prompt to remove duplicates.

    So this is not just one issue mentioned in this, so I would say GA Node is itself having issues.
