RSpec：失败 Cabybara Webkit InvalidResponseError

Question

我在十几个失败的规格上遇到了这个错误。我团队中的其他开发人员（以及我们的 CI）没有看到这些失败的规范，所以这是我的工具包本地的问题。

编辑：前 6 行摘自 capybara-webkit 的 :webkit_debug 驱动程序：

...

  1) User edits profile information
     Failure/Error: click_on t('users.edit')
     Capybara::Webkit::InvalidResponseError:
       Unable to load URL: http://127.0.0.1:53899/myprofile?as=1089 because of error loading https://dialog.filepicker.io/dialog/comm_iframe/: Unknown error
     # ./spec/features/users_spec.rb:30:in `block (2 levels) in <top (required)>'
     # ./spec/support/background_jobs.rb:14:in `block (3 levels) in <top (required)>'
     # ./spec/support/background_jobs.rb:5:in `run_background_jobs_immediately'
     # ./spec/support/background_jobs.rb:13:in `block (2 levels) in <top (required)>'

我该如何解决这个问题？这是否与 AngularJS 相关？！？

Edit2: 在visit 路径上抛出错误（见下文）。在打开一个空白页面之前添加save_and_open_page 一行。在第 30 行之后放置任何内容都不会因为错误而被调用。在 29 上添加 binding.pry 可以让我进入控制台，但我不确定我应该寻找什么来解决这个问题。

     25:   scenario 'edits profile information', js: true do
     26:     new_avatar = 'http://example.com/avatar.png'
     27:     user = create(:user)
     28:
  => 29:     binding.pry
     30:     visit myprofile_path(as: user)
     31:     click_on t('users.edit')
     32:     edit_profile(name: 'Edit User', avatar: new_avatar)
     33:     visit myprofile_path
     34:
     35:     expect(page).to have_text('Edit User')

最终完全阻止了这些请求spec_helper.rb：

  config.before :each, js: true do
    page.driver.browser.url_blacklist = [
      "https://dialog.filepicker.io",
      "https://www.filepicker.io"
    ]
  end
