I am trying to user omniauth-twitter for my website, but whenever I click on twitter login, I get this error

undefined method `persisted?' for []

omniauth_callbacks_controller.rb file...

def twitter
# You need to implement the method below in your model
@user = User.find_for_twitter_oauth(request.env["omniauth.auth"], current_user)

if @user.persisted?
  flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Twitter"
  sign_in_and_redirect @user, :event => :authentication
else
  session["devise.twitter_data"] = request.env["omniauth.auth"]
  redirect_to new_user_registration_url
end
end

User.rb file... 

def self.find_for_twitter_oauth(access_token, signed_in_resource=nil)
data = access_token.extra.raw_info
if user = User.where(:email => data.email)
  user
else # Create a user with a stub password. 
  User.create!(:name => data.name, :email => data.email, :password => Devise.friendly_token[0,20]) 
end
end

Any idea?
