@SunMarc it's the other way around, the chat shouldn't pass the request ID (it's not a field in the API) 🤗

I thought this was already solved, a user opened a related PR a few days ago. Perhaps not 🤔

Yeah, it is not part of the create oai api but this is why we are passing it in extra_body + TransformersCompletionCreateParamsStreaming no so that we can pass it in generate_chat_completion just like generation_config no ?
In generate_chat_completion, we try to get the request_id also request_id = req.get("request_id", "req_0")

@SunMarc that is logic that should be removed :p

The ID is something that is created by the server at generation time, mostly for internal server logging purposes. It is returned by the server (API), but not passed through a request.

[SunMarc]

Oh okay ! Then i'll just remove the request id from the extra_body then !

[SunMarc]

updated the logic in chat to not deal with request id ;)

[LysandreJik]

Ok!
