Use of proxies kwarg in httpx==0.28.0

[DJRHails]

Confirm this is an issue with the Python library and not an underlying OpenAI API

• This is an issue with the Python library

Describe the bug

httpx version 0.28.0 removes the deprecated proxies argument; this argument is hardcoded in the library at the moment.

To Reproduce

1. Update to httpx version 0.28.0

Code snippets

  File "/var/lang/lib/python3.10/site-packages/openai/_client.py", line 337, in __init__
    super().__init__(
  File "/var/lang/lib/python3.10/site-packages/openai/_base_client.py", line 1438, in __init__
    self._client = http_client or AsyncHttpxClientWrapper(
  File "/var/lang/lib/python3.10/site-packages/openai/_base_client.py", line 1335, in __init__
    super().__init__(**kwargs)
TypeError: AsyncClient.__init__() got an unexpected keyword argument 'proxies'

OS

Python version

This is causing a fresh install of openai to be broken currently.

Here's a reproducer: (Dockerfile)

from alpine:edge

RUN apk update
RUN apk add python3 py3-pip

RUN pip install  --break-system-packages openai
RUN python -c 'import openai; client=openai.AsyncOpenAI(api_key="X")'

Gives:

 => ERROR [5/5] RUN python -c 'import openai; client=openai.AsyncOpenAI(api_key="X")'                              0.4s

Having this issue too, with the synchronous client. A temporary fix I've found is to hardcode the httpx version in my requirements to the previous release, which is 0.27.2.

Just adding httpx==0.27.2 makes my code work again.

Hi, thank you for the reports, we (@stainless-api) are actively working on a fix.

Edit: we have a patch under review right now and expect to push it to this repo in a few minutes

[RobertCraigie]

Thanks for the reports, this will be fixed shortly

[dgellow]

Should be fixed once #1905 gets merged (all the credits to the amazing @RobertCraigie for the quick fix)

[RobertCraigie]

Sorry for the delay, we're trying to get a hold of someone with the credentials to publish a new release.

[stainless-app]

Fixed by #1905

@dgellow @RobertCraigie In the pyproject.toml file, the httpx version is defined as httpx>=0.23.0, <1. Isn't this too wide? It seems to me the dependent libraries versions should only include the current and tested versions. But <1 allows many future upgrades that can potentially break stuff like the current issue. Other dependent libraries are defined in the same manner and seems to have the same issue.

[dgellow]

Hi @vvaezian, thanks for pointing that out. I tend to agree, though I'm not sure how strict the version range should be in this specific context. That's something we identified and will be discussing today as part of our internal post-mortem for that httpx v0.28.0 incident. I expect we will share an update later today in this thread.
