ActionController::UnknownFormat (ActionController::UnknownFormat):

This happens with Devise when working with API only Rails app.
Solution: Add   respond_to :json in the controller.

ActiveModel::UnknownAttributeError (unknown attribute 'user' for User.):

Devise throws this error.

Solution:

Don't use the protected method signup_params. I used my own method:

  def allowed_params
    params.permit(:first_name, :email, :password, :password_confirmation)
  end 

the build_resource call uses this method.

    build_resource(allowed_params)

I copied the create action from Devise::Registrations controller and customized it:

  def create
    build_resource(allowed_params)
    
    resource.save
    if resource.persisted?
      if resource.active_for_authentication?
        sign_up(resource_name, resource)
        respond_with resource, location: after_sign_up_path_for(resource)
      else
        expire_data_after_sign_in!
        respond_with resource, location: after_inactive_sign_up_path_for(resource)
      end
    else
      clean_up_passwords resource
      set_minimum_password_length
      respond_with resource
    end
  end
