Do not use tools param in stream request!

request.stream = False

If you give a tools param in your request and set stream=True, then the output format will be changed by the server and you will get nothing by for grammar (no error will be raised), because the two processing are complete different in the client:

stream -> received with generator of chunks: generater -> async for chunk in result:
non-stream-> received with a fixed result chunk -> use it direct

So, I think if the server does not support stream with tools, then it will be better to return a http error than changing the return method so that the developers can know what should be done or not.
