uc_open_with_reconnect doesn't work in Docker

[PavelBelskiData]

I have a SB based scraper that perfectly works locally on MacOS - it opens the listing page, clicks protected element and reads text.

url = "https://www.otomoto.pl/osobowe/oferta/ford-mondeo-ford-mondeo-mk4-ID6H0DTK.html"
with SB(uc=True, headless=True, xvfb=True) as sb:
       print("SB created")

       sb.driver.uc_open_with_reconnect(url, reconnect_time=6)

However, it doesn't work when I am trying to run the code in docker. The SB object is created but it is not able to open the page. After a couple of minutes processing the error is:

Traceback (most recent call last):
  File "/usr/local/lib/python3.10/dist-packages/seleniumbase/core/browser_launcher.py", line 496, in uc_open_with_reconnect

    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.InvalidSessionIdException: Message: invalid session id

I have tried different combinations of options headless, xvfb, incognito and none of them worked.
I've also tried the cdp mode which also didn't work.

I build my Docker image with --platform linux/amd64.

The same Docker container can open other websites:
https://gitlab.com/users/sign_in
and even https://www.otomoto.pl - the home page of the website I am trying to open.

Please help run the code in Docker.

Also, are there better/simpler options for scraping automation?

CDP Mode replaces regular UC Mode, so I would need to see the stack trace you get when using CDP Mode for that. (The uc_open_with_reconnect() method is from regular UC Mode). Also, Docker leaves a detectable fingerprint, so if you're going for stealth, I wouldn't use Docker. Use GitHub Actions instead. Lots of examples of stealthy GitHub Actions jobs in https://github.com/mdmintz/undetected-testing/actions.
