如何在陈旧的Rails应用程序中识别新javascript错误的来源

试图“解冻”一个已有一年历史的项目，却发现一些奇怪的javascript错误。我没有太多的运气去寻找解决方案

我猜这与我的开发盒上的某些东西太新（或太旧）而无法使用此代码库有关，但不确定解决此问题的最佳方法

有什么想法可以解决这个问题吗

谢谢你的帮助

以下是规格：

  # ./spec/support/helpers/comments_page_helpers
  ...
  def open_image_comments_modal(section_position:, photo_position:)
    selector = "editable-section:nth-child(#{section_position}) " \
      "li.photo:nth-child(#{photo_position})"

    within selector do
      find('a.image-wrapper img').click        ### <== line #23
    end

    expect(page).to have_css('.modal-comments-container')
  end
  ...

。/spec/support/helpers/comments\u page\u helpers
...
def打开图像注释模式（截面位置：，照片位置：）
选择器=“可编辑部分：第n个子项（#{section\u position}）”\
“李。照片：第n个孩子（#{photo_position}）”
在选择器do内
查找（'a.image-wrapper img'）。单击#####JS错误会告诉您问题所在-您无权访问
/api/v1/comments
，这是从请求返回到您自己的应用程序吗？还是来自外部服务的请求？此外，你使用的是恶鬼，这基本上相当于6-7岁版本的Safari在这一点上。如果你正在用JS/CSSrequest for
/api/v1/comments
对我们自己的应用程序进行回调，那么最好通过selenium驱动程序使用headless Chrome或Firefox。不确定为什么在测试期间应用程序运行时它不会响应？该应用程序已经“休眠”一年了。我被要求“解冻”它。在迁移到chromedriver之前，我想先通过以前的测试。正在寻找解决此问题的最佳方法。它正在响应一个401未授权错误——请检查rails test.log以了解请求被拒绝的原因。
5) Comment creation for image behaves like added comment adds single comment
     Failure/Error: find('a.image-wrapper img').click

     Capybara::Poltergeist::JavascriptError:
       One or more errors were raised in the Javascript code on the page. If you don't care about these errors, you can ignore them by setting js_errors: false in your Poltergeist configuration (see documentation for details).
