Can someone please explain how to set the JSON object structure for the output of a GPT Message a Model node in n8n? Before, you would just tell it in the system prompt how to return the JSON object and turn on 'return output as JSON'. Now, there are a lot more options in the Message a Model node. I just want to tell it to ONLY output my object (in green) and not output any of the stuff before (in red).
Anyone know how to do this with the recent update? Thanks.
