What you have set up is great, I am trying to do the same but I can't, could you help me and tell me what you have put in the AI Task? This is where I have the problem, and when I put the expression allways I send it to a node that always responds to ChatGPT with a {{event.preview}} and always interprets that the text response is the one I give to ChatGPT, therefore it is My answer duplicates, do you know how to solve this? Thank you so much.
