String indices must be integers (Google Login)

[kmemonahmed]

When trying log in with google with Django version 4.1.5 and Python 3.10 it Always gives this error,

[Housain-maina]

The reason why this is happening is because the 'complete_login' method in 'GoogleOAuth2Adapter' class is trying to access 'response["id_token"]' and the key does not exist. But since 'response' returns only the value of 'id_token' you can create a custom 'GoogleOAuth2Adapter' by modify it the following way:

from allauth.socialaccount.providers.oauth2.client import OAuth2Client, OAuth2Error
from dj_rest_auth.registration.views import SocialLoginView
from allauth.socialaccount.providers.google.provider import GoogleProvider
from allauth.socialaccount.providers.google import views as google_views
from allauth.socialaccount.providers.oauth2.views import OAuth2Adapter
import jwt


class GoogleOAuth2Adapter(OAuth2Adapter):
    provider_id = GoogleProvider.id
    access_token_url = google_views.ACCESS_TOKEN_URL
    authorize_url = google_views.AUTHORIZE_URL
    id_token_issuer = google_views.ID_TOKEN_ISSUER

	def complete_login(self, request, app, token, response, **kwargs):
	        try:
	            identity_data = jwt.decode(
-               response["id_token"],		# removed line
+				response,					# added line
	                # Since the token was received by direct communication
	                # protected by TLS between this library and Google, we
	                # are allowed to skip checking the token signature
	                # according to the OpenID Connect Core 1.0
	                # specification.
	                # https://openid.net/specs/openid-connect-core-1_0.html#IDTokenValidation
	                options={
	                    "verify_signature": False,
	                    "verify_iss": True,
	                    "verify_aud": True,
	                    "verify_exp": True,
	                },
	                issuer=self.id_token_issuer,
	                audience=app.client_id,
	            )
	        except jwt.PyJWTError as e:
	            raise OAuth2Error("Invalid id_token") from e
	        login = self.get_provider().sociallogin_from_response(request, identity_data)
	        return login

then

class GoogleLogin(SocialLoginView):
    adapter_class = GoogleOAuth2Adapter
    client_class = OAuth2Client

I'll create a PR for this fix.
