Hi @kuldude @Nikita, for the error where 'message[0].content' is missing, it arises when the user prompt is undefined.
I'm guessing that the property that is being used in the user prompt input is not the same as what is being sent in by the request.
The Jam shows that the property "prompt" of the Body is how the message is sent in. Can you check if that same property is used in the "User Prompt" input of the node
