Did you ever find a solution? I’m on mobile, and the Pastebin formatting is a bit off, so I can’t read the compose file very well. However, I suspect the error is related to this line:

24 # - WEBDRIVER_URL=browser-chrome:4444/wd/hub

Since a colon (‘:’) is used to indicate a volume, it makes sense that the error is about a missing volume. Try wrapping the line in double quotes like this:

24 # - “WEBDRIVER_URL=browser-chrome:4444/wd/hub”

to see if that fixes the error.
