What happened?

when using the docker image, cannot find the filename.crdownload in anyplace.
I'm using python,and selenium is a module for function not distribution test.
Need help!!!
Code for selenium initilization:

prefs = {"download.default_directory": download_path}
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_experimental_option('prefs', prefs)
driver = webdriver.Chrome(options=chrome_options)

Also facing this issue

Adding a little more info in ruby:

I use setup headless_for_download like this:

def setup_headless_for_download
    bridge = page.driver.browser.send(:bridge)

    path = "/session/#{bridge.session_id}/chromium/send_command"
    path = ENV['SELENIUM_URL'] + path if ENV['SELENIUM_URL'].present?

    bridge.http.call(
      :post,
      path,
      cmd: 'Page.setDownloadBehavior',
      params: {
        behavior: 'allow',
        downloadPath: PATH
      }
    )
  end

And my github actions workflow is set up like this:

run_system_tests:
    runs-on: ubuntu-latest
    services:
      postgres:
        image: postgres:latest
        ports:
          - 5432:5432
      selenium:
        image: selenium/standalone-chrome:latest
        ports:
          - 4444:4444
        volumes:
          - ${{ github.workspace }}:${{ github.workspace }}

There are a few things involved here:

• Headless has always had an issue with downloads. Hence https://www.selenium.dev/blog/2023/headless-is-going-away/ and https://developer.chrome.com/articles/new-headless/.
• If you are running this code on Linux, be sure to check https://github.com/SeleniumHQ/docker-selenium#mounting-volumes-to-retrieve-downloaded-files
• When overriding CMD, I'd say you are on your own because these images use supervisor to manage all processes.
