How to only return content to internal chat, not the full JSON

Questions

Describe the problem/error/question

I build a simple chat message → OpenAI → respond to webhook flow.
In the respond to webhook Parameters I select Respond with text and a json expression. Nevertheless the whole JSON object gets returned

What is the error message (if any)?

No error

Please share your workflow

Share the output returned by the last node

{ "index": 0, "message": { "role": "assistant", "content": "Rock and Roll", "refusal": null, "annotations": [] }, "logprobs": null, "finish_reason": "stop" }

Hi Stephan_Wissel welcome to n8n community :n8n:

I think you dont need that respond to webhook node since you just using chat triiger so the output just the content

Thank you for your swift reply, very much appreciated. I must be missing something. Deleted the webhook and still get the full JSON in the output.

Hi Stephan, try disconnecting and reconnecting everything, or you could remove the nodes and restart. Sometimes it’s just a glitch. Alternatively, you can use this one.

ok just found out you are using openAI node, so change it to using ai agent or LLM Agent if you want work with Chat Trigger
