is not JSON serializable - django social auth Facebook login

Question

I'm trying to login with Facebook with Django-Social-Auth But I'm getting this error:

TypeError at /complete/facebook/
datetime.datetime(2014, 4, 25, 22, 20, 14, 665216, tzinfo=<UTC>) is not JSON serializable

This is my login template:

<a href="{% url 'socialauth_begin' 'facebook' %}">Login with FB</a>

My settings:

SOCIAL_AUTH_DEFAULT_USERNAME = 'new_social_auth_user'
SOCIAL_AUTH_UID_LENGTH = 16
SOCIAL_AUTH_ASSOCIATION_HANDLE_LENGTH = 16
SOCIAL_AUTH_NONCE_SERVER_URL_LENGTH = 16
SOCIAL_AUTH_ASSOCIATION_SERVER_URL_LENGTH = 16
SOCIAL_AUTH_ASSOCIATION_HANDLE_LENGTH = 16

SOCIAL_AUTH_ENABLED_BACKENDS = ('facebook')

Answer 1

you should just add

 SESSION_SERIALIZER='django.contrib.sessions.serializers.PickleSerializer'

to settings
