Answer 1

Chrome 75 defaults to W3C mode, which doesn't specify a way to get log access.

The short term fix for this issue is to disable w3c via chromeOptions.

Capybara.register_driver :headless_chrome do |app|
  capabilities = Selenium::WebDriver::Remote::Capabilities.chrome(
    chromeOptions: { args: %w[headless window-size=1280,800], w3c: false },
  )

  Capybara::Selenium::Driver.new app,
                                 browser: :chrome,
                                 desired_capabilities: capabilities
end

Answer 2

in recent selenium-webdriver (4.4.0) with recent Chrome (105), manage.logs is gone but this works:

page.driver.browser.logs.get(:browser)
