[Issue]: Not possible to save intermediate ChatResult history once conversation fails

[ArturDev42]

Describe the issue

As described in the tutorial, I am using chat_result = user_proxy.initiate_chat(assistant, message=message, max_turns=cfg.max_turns). If there is no error, then the chat is successfully saved in chat_result. However, if an error occurs at some point during the conversation, the conversation until that point is not saved.

I see that in initiate_chat the ChatResult is only saved at the end and not while messages are sent:

ag2/autogen/agentchat/conversable_agent.py

Line 1125 in 1fb6248

chat_result = ChatResult(

Is it possible to save intermediate results (e.g. chat_history, cost, etc.) after every interaction between user proxy and agent until an error occurs? Thanks for the help!
