Heroku Rails內部服務器錯誤

當我嘗試在heroku上部署我的Rails應用時，出現500內部服務器錯誤。它在我的本地機器上正常工作，所以我不確定這裏有什麼問題。似乎是家庭控制器上的「會話」。這是我的日誌：Heroku Rails內部服務器錯誤

，這裏是我的home_controller.rb

class HomeController < ApplicationController 
    before_filter :login_required 

    def index 
     @user = current_user 
     @user.profile ||= Profile.new 
    @profile = @user.profile 
    end 

end

是否有一些我的路由設置的方式嗎？還是我的身份驗證？（我正在使用Bort的寧靜認證）
