This package stopped working after upgrading to Django 4.2 and higher but works with Django versions lower than 4.2
in Django versions 4.2 and higher the callback url that Okta connects to is no longer processed because the url definition of a callback url has an additional /:
https://github.com/AzMoo/django-okta-auth/blob/main/okta_oauth2/urls.py#L7

In the Readme of the project the callback url is defined without the slash:

Something in the url processing logic in Django has changed between versions 4.1 and 4.2 that led to the outcome that the callback view that sets the session tokens was no longer called and therefore the session tokens were no longer set.
Instead of setting the session token a redirect was triggered to the login page, which tried to call the callback url again and this lead to an infinite loop between the two views.

By removing the trailing slash from the callback url this issue is fixed and this fix is backwards compatible.
