Troubleshooting Slack Agent Trigger Issues and Errors

Hi all! I've been trying to create a slack agent, but the trigger is not working. It keeps asking for '{"type":"lindyStateGraph","data":{"nodes":[],"edges":[],"stickyNotes":[]}}' (Perform the action to begin testing). I tried with your template, and then by myself and none of them work. What can it be? I connected to the correct slack account. Thanks a lot
