Ruby on rails 如何使用rpsec修复Ruby中Selenium Webdriver中过期的执行

我试着运行一个测试，回答用angularjs完成的表单。 当我运行测试时，过了一段时间后，我一直得到如下错误。我试图用StandardError捕获异常，但我想找出解决此问题的方法

• Ruby:Ruby 2.1.5p273（2014-11-13修订版48405）[i386-mingw32]
• Selenium:SeleniumServerStandalone-2.47.1.jar和SeleniumServerStandalone-3.4.0.jar

（我尝试了两个Selenium服务器，看看最新的服务器是否能够修复它，但没有运气）

您能否显示导致此错误的代码？它看起来将在./lib/api/page_model.rb的第175行左右。请参阅上面更新的代码。
