NoMethodError（未定义的方法'text'为nil：NilClass）发生了什么？

此错误出现在我的heroku日志中，我不确定发生了什么。该应用程序无法正常运行，并在许多不同的位置打破。奇怪的是，这是从哪里开始发生的。过去7天没有变化。周五一切都正常，这意味着这个错误在过去4天内开始发生。NoMethodError（未定义的方法'text'为nil：NilClass）发生了什么？

是否有任何宝石依赖项可能在周末更改/更新，可能会导致此错误？

发布是错误

你在'lib/my_company/delayed_job_wrapper.rb'的第70行调用方法'text'的对象是nil ...这就是错误信息告诉你的那个 –

没有方法“text”在该文件中调用。 – Smooth

请张贴您的控制器。 – Thanh

的问题是，Heroku的宝石已被否决，所以我取代了Gemfile中的宝石 “的Heroku” 与 “Heroku的-API”
