What
Allow
messages[].contentto benullforassistant/toolroles to match OpenAI Chat Completions behavior whentool_callsare present.Why
OpenAI-compatible clients may send an assistant message with
tool_callsandcontent: null. Current Pydantic validation rejects it with:ValidationError: body.messages.content.str - Input should be a valid string.This breaks tool-call flows.
Changes
MessageItem.content:Union[str, list, None](defaultNone)validate_request: acceptcontent is Noneforassistantandtoolroles; keep rejecting empty content foruser/system/developer.Notes
Minimal change; no behavior change for normal string/list content.
