[baskaryan]

these are different i believe. 'id' is the object id, 'call_id' is what you'll use to refer to this tool call when returning the output

[baskaryan]

'call_id' maps to what we store as toolCall.id

[baskaryan]

for now was thinking of throwing the new 'id' for all tool calls in AIMessage.additionalKwargs['openai_tool_call_ids'] or something like that. and it'd be a map from call_id -> id

[baskaryan]

smth like

            if tool_calls := lc_msg.tool_calls:
                if not lc_msg.additional_kwargs.get("__openai_function_call_ids__"):
                    raise ValueError(...)
                function_call_ids = lc_msg.additional_kwargs["__openai_function_call_ids__"]
                for tool_call in tool_calls:
                    function_call = {
                        "type": "function_call",
                        "name": tool_call["name"],
                        "arguments": tool_call["arguments"],
                        "call_id": tool_call["id"],
                        "id": function_call_ids[tool_call["id"]],
                    }
                    updated_payload["input"].append(function_call)
