Fix Plan

To resolve the issue of a phantom entry appearing in the sessions.list response, we need to modify the backend logic to filter out store-level placeholder entries.

Code Changes

We will add a check to ensure that only sessions with a valid sessionId and non-null updatedAt value are included in the response.

def get_sessions(agent_id):
    # Existing code to retrieve sessions
    sessions = sessions_store.list(agent_id)
    
    # Filter out phantom entries
    filtered_sessions = [s for s in sessions if s.get('sessionId') and s.get('updatedAt') is not None]
    
    return filtered_sessions

Alternatively, if you're using a database query to retrieve sessions, you can modify the query to exclude rows with null updatedAt values and no sessionId.

SELECT * FROM sessions
WHERE agent_id = 'sean' AND session_id IS NOT NULL AND updated_at IS NOT NULL;

Verification

To verify that the fix worked, call the sessions.list endpoint with the same agentId and check that the response no longer includes the phantom entry. The response should only contain real sessions with a sessionId and non-null updatedAt value.

Extra Tips

• Make sure to test the fix thoroughly to ensure that it doesn't introduce any new issues or affect the functionality of other features.
• Consider adding additional logging or monitoring to detect and prevent similar issues in the future.
