Starlette OAuth causes invalid auth argument on HTTPX 0.18.2

[alessandroralc]

After upgrading to HTTPX 0.18.2, the starlette oauth module started to crash.

When i call the oauth authorize_redirect method, i get the following error: Invalid "auth" argument: <httpx._config.UnsetType object at 0x7fb5ac920310>"}

In HTTPX 0.18.1, everything works like a charm.

Could you verify? Thanks in advance.

One helpful thing to do here would be to point us at the specific project/repository - I'm not sure I'd know offhand what "the starlette oauth module" is exactly, without a bit of digging around.

It looks? like that package is using some private implementation detail that it shouldn't be doing, and so has broken on the newer httpx version.

Note that httpx._config.UnsetType includes an underscore on the _config portion, which implies private API space which shouldn't be accessed directly.

I'd expect that the package will want to be using httpx.USE_CLIENT_DEFAULT, which now exists as a piece of public API.

The Starlette Oauth Module is provided by the AuthLib -> https://pypi.org/project/Authlib/
I'm using the version 0.15.4 (most recent)

@tomchristie , i discovered that already exists an issue on Authlib github project that is solving this problem ( lepture/authlib@4027670 ). Thanks for the attention.
