Error: Client.__init__() got an unexpected keyword argument 'proxies'

Getting this error from the test suite, but only if I upgrade httpx to 0.28.1.

Error: Client.__init__() got an unexpected keyword argument 'proxies'

https://github.com/encode/httpx/releases/tag/0.28.0 says:

The deprecated proxies argument has now been removed.

I'm not using that myself, maybe the test framework is? pytest-httpx

Upgrading to pytest-httpx==0.35.0 (the latest version) did not fix the error, despite that version promising compatibility with httpx==0.28.0:

• Update to latest httpx Colin-b/pytest_httpx#174

This is hard to debug because the exception is being swallowed somewhere and turned into a system exit.

This change helps with debugging:

Got me this traceback, maybe the problem is in the openai client library?

self = <openai._base_client.SyncHttpxClientWrapper object at 0x122765d20>, kwargs = {'base_url': 'https://api.openai.com/v1', 'follow_redirects': True, 'limits': Limits(max_connections=1000, max_keepalive_connections=100, keepalive_expiry=5.0), 'proxies': None, ...}

I upgraded my local environment from openai==1.37.0 to openai==1.59.8 and now all but one of the tests pass - it definitely fixed this problem.

[simonw]

... that other test failure was because of my new debugging code. The solution here is to upgrade openai.

[simonw]

Here's where OpenAI fixed this problem:

• fix(client): compat with new httpx 0.28.0 release openai/openai-python#1904

[simonw]

And they shipped the release here:

• release: 1.55.3 openai/openai-python#1905

So depending on openai>=1.55.3 will fix the problem.
