Bug

Could not start a new session. Response code 500. Message: session not created: probably user data directory is already in use,

Go into the /home/seluser director in the container and run rm -rf ~/.config/google-chrome/Singleton*

One-liner : rm -rf /home/seluser/.config/google-chrome/Singleton* && exit

If it doesn't work, the log can be found in the seluser chrome profile folder in the file chrome_debug.log

Could not start a new session. Response code 500. Message: session not created: Chrome instance exited. Examine ChromeDriver verbose log to determine the cause.

The log can be found in the seluser chrome profile folder in the file chrome_debug.log.

If the log file only says that the chrome profile folder seems to be in use by another chrome application, there is probably a problem with a file in the chrome profile folder like a version change. The best thing to do is to delete the folder.
