I am not sure about the SOCIAL_AUTH_PIPELINE settings, i have just copied them , which are like

SOCIAL_AUTH_PIPELINE = (
    'social.pipeline.user.create_user',
    'social.pipeline.social_auth.social_user',
    'social.pipeline.social_auth.associate_user',
    'social.pipeline.social_auth.load_extra_data',
    'social.pipeline.user.user_details',
)

Can you please explain whats the issue and how exactly this SOCIAL_AUTH_PIPELINE works ?
