Issues with REMOTE_AUTH_BACKEND variable and social_core for SSO

Current Behavior

Netbox setup is working without SSO. I've added the following to the netbox.env file:

REMOTE_AUTH_ENABLED=true
REMOTE_AUTH_AUTO_CREATE_USER=true
REMOTE_AUTH_BACKEND='social_core.backends.open_id_connect.OpenIdConnectAuth'
SOCIAL_AUTH_OIDC_OIDC_ENDPOINT='<endpoint>'
SOCIAL_AUTH_OIDC_KEY='<oidc_client_id>'
SOCIAL_AUTH_OIDC_SECRET='<oidc_client_secret>'

The error is No module named "'social_core". Notice the strong quote included in the module name. For some reason the configuration.py script includes that quote as part of the library string.

If I enter just the string without quotes I can see the OIDC login button.

REMOTE_AUTH_BACKEND=social_core.backends.open_id_connect.OpenIdConnectAuth

However, when I press it I get:

<class 'TypeError'>
unsupported operand type(s) for +: 'NoneType' and 'str'

I'm at a loss. Can anyone help?

Expected Behavior

Get redirected to the OIDC login page.
