Describe the problem/error/question

Infinite Loop in Messenger AI Workflow:

Reponse is sent automatically to the user in messenger, and it never stops. I need to deactivate the workflow manually.

This is happening in production stage.

I tried several approach: Added webhook at the end of HTTP node with response OK to send facebook message that I have received the message.

I have added ‘if’ node before ‘AI’ node and added 2 conditions to check so the loop can be broken based on empty message or same sender (messenger user) and recipient id (page id)

I tried to match them by hardcoding the page id. Nothing worked.

Thank you very much for your patience. I am very new to this platform. Need Help…

What is the error message (if any)?

No error message as there is no error in the workflow apparently
