      - db
      - rabbitmq
      - selenium_hub
    env_file: secrets.env
    volumes:

This error message...

selenium.common.exceptions.InvalidCookieDomainException: Message: invalid cookie domain

...implies that an illegal attempt was made to set a cookie under a different domain than that of the current document.


Details

As per the HTML-Living Standard Specs a Document Object may be categorized as a cookie-averse Document object in the following circumstances :

  • A Document that has no Browsing Context.
  • A Document whose URL's scheme is not a network scheme.
