i have this dockerfile

I have this seleniumbase script:

from seleniumbase.undetected import cdp_driver
async def get_webdriver_nd(proxy_data=None) -> cdp_driver.browser.Browser:
    logging.debug("Launching web browser with nodriver...")
    proxy = None
    if type(proxy_data) is dict and proxy_data != {}:
        server = proxy_data.get("server")
        username = proxy_data.get("username")
        password = proxy_data.get("password")
        if server and username and password:
            proxy = f"{username}:{password}@{server}"
        elif server:
            proxy = server
    return await cdp_driver.cdp_util.start_async(
        proxy=proxy,
    )

And I have this error

I am unable to run headful chrome on production AWS EC2 with seleniumbase while I can make it work locally
Any help on why this can happen?

Any "slim" Dockerfile is going to be missing important dependencies, eg: https://stackoverflow.com/a/49710327/7058266.

Note that there's already a Dockerfile for regular SeleniumBase use: SeleniumBase/Dockerfile.

However, Docker leaves a detectable fingerprint, which makes Docker incompatible with UC Mode / CDP Mode.
If you want to run undetectable automation on a Linux server, GitHub Actions works well for that, as discussed in my YouTube video: https://www.youtube.com/watch?v=Mr90iQmNsKM.

(AWS runs on a non-residential IP-range, which means running from there would be detectable.)
