Streaming errors don't include the correct error

Aware there is some effort being made here, but opening the issue just in case.

For example, when streaming and openai returns a bad request, it will just return a 'invalid status code', without the actual body of the request. Currently I turn streaming off if I have issues. Still, it's tedious.

I'm concerned solving this might be a bit more involved, since event source does some weird error mapping as well.

Glad to hear there is effort being made here, commenting to say I see the same issue.

In my case, this happens when I try to use reasoning with gpt-5 models via the Responses API.

It just shows Invalid status code: 400 Bad Request and nothing else.

EDIT: *with streaming true

Came to also request support for this, currently I am retrying 429 errors by doing string comparisons on the error text and there must be a better way to get access to the underlying error. Any way I can help move towards a solution?
