User exists error on signup ruby on rails acts_as_paranoid - ruby-on-rails

Question

I'm having an error on signup. Console indicated its an error "User exists" however i think its a problem with acts_as_paranoid conflicting with devise gem. Can you please help?
Gem - Device & ActsAsParanoid
It was working fine until i added acts_as_paranoid gem
Console response:

Answer 1

I made an error! The user author_id relationship was wrong. This has fixed.
belongs_to :author, class_name: 'User', foreign_key: 'author_id', optional: true
