Unable to download a file when clicking on a link

[gopalagrawal]

I'm using python + Selenium webdriver. I have the webdriver configured as follows:

    options = webdriver.ChromeOptions()
    prefs = { 
        'download.default_directory'                :  "/home/ga/Downloads", 
        'profile.default_content_settings.popups'   : 0,
        'download.prompt_for_download'              : False
    }
    options.add_experimental_option('prefs', prefs)

    driver = webdriver.Remote( 'http://127.0.0.1:4444',   DesiredCapabilities.CHROME, options=options)

But when doing a driver.get( url-to-a-csv-file ) nothing is downloaded. Any idea what else needs to be done. If this could be documented, it would help immensely. Most likely, its some settings for the chromedriver that's missing or perhaps the docker container runs chrome in such a way as to prevent the download of file.
