Looking for someone to help me out in the project I'm currently developing: a trainable chatbot. I've already connected the ChatGPT API and changed the JSON's body to both make the chat work (conversational) and make the bot context-aware. I am now having some difficulties with making it trainable. I came up with the idea of making the JSON's "role: system" part of the body dynamic (since in order to make the messages part dynamic I changed the JSON's "role: user" part of the body) but have already tried that and the preview of the bubble app returns "400 error". This is the only issue I've encountered so far and I am currently looking for someone to help me out with this specifically.
