Using django-allauth I am unable to log in with Twitch

Question

UPDATE - I got allauth working with google following the same steps I tried for Twitch.

First off I'm quite new to programming anything. This is my first project outside of tutorials.

I'm trying to use django-allauth to log in using Twitch. I'm starting my project using coockiecutter-django that sets up django-allauth automatically, but without any social authentication set up. I can log in just fine with an account made on my site.

After adding 'allauth.socialaccount.providers.twitch', to the INSTALLED_APPS, a Twitch link appears on the log in page. I registered my app at http://www.twitch.tv/kraken/oauth2/clients/new and copied everything into the admin social application page.

After clicking on the Twitch log in link, I get the following error:

Environment:

I'll try to provide everything in my project code that I think is relevant. If I'm forgetting something please let me know.

settings.py (renamed common.py in coockiecutter-django)

INSTALLED_APPS = (
    'allauth',
    'allauth.account',
    'allauth.socialaccount',
    'allauth.socialaccount.providers.twitch',
)

TEMPLATE_CONTEXT_PROCESSORS = (
    'django.core.context_processors.request',
    "allauth.account.context_processors.account",
    "allauth.socialaccount.context_processors.socialaccount",
)

AUTHENTICATION_BACKENDS = (
    "django.contrib.auth.backends.ModelBackend",
    "allauth.account.auth_backends.AuthenticationBackend",
)

SITE_ID = 1

ACCOUNT_AUTHENTICATION_METHOD = "username"
ACCOUNT_EMAIL_REQUIRED = True
ACCOUNT_EMAIL_VERIFICATION = "mandatory"

AUTH_USER_MODEL = "users.User"
LOGIN_REDIRECT_URL = "users:redirect"
LOGIN_URL = "account_login"

urls.py

url(r'^users/', include("users.urls", namespace="users")),
url(r'^accounts/', include('allauth.urls')),

All info in the Twitch registration page and my admin page should be matched up. I copy/pasted it all and checked it several times. Removing all info and entering it again.

You need to add the user_read scope so that the callback request contains the _id parameter

Add this to your settings.py

 SOCIALACCOUNT_PROVIDERS = {
            "twitch": {"SCOPE": ["user_read"]},
    }
