Open angpao opened this issue 10 months ago • 4 comments

I have two frontend (AI-CHATBOT) and backend (fastapi+langraph) when send message from frontend to backend then the backend send stream text to call tool-call and also argument (json data) to give frontend show UI form then user entry data then send to backend again then backend send result to frontend on chat. How to config?
