Details on AI Agent function call POST requests

Describe the problem/error/question

I've set up a custom server that's compatible with the OpenAI API and have successfully tested it with Python's API for function calls, using the api_key and base_url within the openai module.

However, when I use the AI agent function call feature, it fails on the second request after the initial request with the OpenAI Chat node and the subsequent tool result. I'm trying to retrieve the actual HTTP POST request details via a proxy server, but I've noticed this functionality hasn't been implemented yet (refer to Add proxy setting retrieving for chat open ai node, to fix https://github.com/n8n-io/n8n/issues/10901 by jasonliusz · Pull Request #13678 · n8n-io/n8n).

Could someone please inform me about the request body used during the function call with the OpenAI Chat node?

What is the error message (if any)?
