Not tryna convince you lol. Just going through basic troubleshooting.
I don't even have all the information.
But that is why there is a big sign that says:
The Functions feature is being deprecated in favor of Tools.
For new functions, please use tools instead. We're working on a solution to migrate your existing functions over to make this a seamless transition once we're ready to remove this from the UI.
Also that is not how it works - it will also receive data because its a webhook. You can call it send wrong, correct data etc. Also we are talking about the response of the assistant. Not just mapping something somebody said.
