Django Social Auth-Google：AttributeError：'NoneType'对象没有属性'provider'

Question

我尝试通过Google登录时收到此错误，我已经尝试了所有我能想到的东西，所以类似的问题似乎也无济于事。我有这样的自定义用户模型设置：

models.py

from django.contrib.auth.models import AbstractUser
from django.db import models
class Departments(models.Model):
    name = models.CharField(max_length=255, unique=True)
    def __str__(self):
        return self.name

class AlluredUser(AbstractUser):
    departments = models.ManyToManyField(Departments)
    def __str__(self):
        return self.username  

forms.py

from django import forms
from django.contrib.auth.forms import UserCreationForm, UserChangeForm
from .models import AlluredUser

class CustomUserCreationForm(UserCreationForm):

    class Meta:
        model = AlluredUser
        fields = ('username', 'email')

class CustomUserChangeForm(UserChangeForm):

    class Meta:
        model = AlluredUser
        fields = ('username', 'email')

社交认证管道

SOCIAL_AUTH_PIPELINE = (
    'social_core.pipeline.social_auth.social_details',
    'social_core.pipeline.social_auth.social_uid',
    'social_core.pipeline.social_auth.auth_allowed',
    'social_core.pipeline.social_auth.social_user',
    'social_core.pipeline.user.get_username',
    'social_core.pipeline.social_auth.associate_by_email',
    'social_core.pipeline.user.create_user',
    'social_core.pipeline.social_auth.associate_user',
    'social_core.pipeline.social_auth.load_extra_data',
    'social_core.pipeline.user.user_details'
)

我猜这与我创建的自定义用户模型有关，因为我事先没有这个问题。任何帮助将不胜感激。

链接上的错误与标题中提到的不符。对于回溯，解决方案只是添加以下内容：

SESSION_COOKIE_SECURE = False
