我试图在rspec Ruby on Rails中使用无头模式的chrome和capybara/selenium,并在尝试单击确认对话框时出现错误

Capybara.register_driver(:headless_chrome) do |app|
  capabilities = Selenium::WebDriver::Remote::Capabilities.chrome(
    chromeOptions: { args: %w[headless disable-gpu test-type window-size=1920x1080] }
  )

  driver = Capybara::Selenium::Driver.new(
    app,
    browser: :chrome,
    desired_capabilities: capabilities
  )

  driver
end

Capybara.server = :puma
Capybara.javascript_driver = :headless_chrome



scenario 'delete movie' do
  login_as user
  visit edit_public_movie_path(movie)

  expect(page).to have_selector('span[ng-click="ctrl.deleteMovie()"]')
  find('span[ng-click="ctrl.deleteMovie()"]').click

  page.driver.browser.switch_to.alert.accept

  wait_for_ajax(wait_after: 1)
  expect(page).to have_content('Click here to upload movie (Max: 500 MB)')
end

并得到了这个错误

 Event movie success delete movie
 Failure/Error: page.driver.browser.switch_to.alert.accept
