I decided to put a google sign in method into my Django website, but I have been encountering errors related to the social_auth_app_django library. For example, at first I got a ValueError (Expected 2 got 1) from one of the utils.py in the library code. Note that I am new to adding google sign in to a Django application.
Here are my version specifications:
Here is my settings.py (note that the API keys will be hidden for security purposes)

Here is the function where the main ValueError is being caused:

module = import_module(mod)
return getattr(module, member)
except (ValueError, AttributeError, ImportError) as e:
print(f"Couldn't import {name}: {e}")

"""
Load backends defined on SOCIAL_AUTH_AUTHENTICATION_BACKENDS, backends will
be imported and cached on BACKENDSCACHE. The key in that dict will be the
backend name, and the value is the backend class.
Only subclasses of BaseAuth (and sub-classes) are considered backends.
Previously there was a BACKENDS attribute expected on backends modules,
this is not needed anymore since it's enough with the
AUTHENTICATION_BACKENDS setting. BACKENDS was used because backends used to
be split on two classes the authentication backend and another class that
dealt with the auth mechanism with the provider, those classes are joined
now.
A force_load boolean argument is also provided so that get_backend
below can retry a requested backend that may not yet be discovered.

I have tried various methods, like changing the rsplit from (".", 1) to (".", 2), as well as a lot of asking questions from AI for help, but none of them worked. As said above, I just kept continously getting errors over and over again. Here is a detailed (very detailed) error message:
Couldn't import s: not enough values to unpack (expected 2, got 1)

Thank you for all possible help.
I fixed my error: The backend name was incorrect.
