Issue
I can register a user successfully, but cannot log in using that user. It shows 401 unautherized at the time. It appears that the parameter arrives in the configuration_sign_in_params method, but the return value of the configuration_sign_in_params method is empty.
All these issues are started from when i set login with social accounts ...Before that everything were fine .
