Python Social Auth NotAllowedToDisconnect at /disconnect/facebook/1/

I'm trying to use logout with Python Social Auth in a Django app, but I'm getting

NotAllowedToDisconnect at /disconnect/facebook/1/

These are my settings:

SOCIAL_AUTH_PIPELINE = (
    'social.pipeline.social_auth.social_details',
    'social.pipeline.social_auth.social_uid',
    'social.pipeline.social_auth.auth_allowed',
    'social.pipeline.social_auth.social_user',
    'social.pipeline.user.get_username',
    'social.pipeline.mail.mail_validation',
    'social.pipeline.user.create_user',
    'social.pipeline.social_auth.associate_user',
    'social.pipeline.social_auth.load_extra_data',
    'social.pipeline.user.user_details'
)



SOCIAL_AUTH_DISCONNECT_PIPELINE = (
    'social.pipeline.disconnect.allowed_to_disconnect',
    'social.pipeline.disconnect.get_entries',
    'social.pipeline.disconnect.revoke_tokens',
    'social.pipeline.disconnect.disconnect'
)

And this is the code I'm using on templates

{{ assoc.provider }} (<a href="{% url 'social:disconnect_individual' assoc.provider assoc.id %}" class="disconnect">Disconnect </a>)
