Element not found with xpath, //html. Error present even when adding Behat configs suggested online.

I have a D9 install with Docksal that will run behat, but I get this error:

    Element not found with xpath, //html
           (WebDriver\Exception\NoSuchElement)

I suspect it has to do with my behat configs.

I have done some research online with the error message and there were suggestions to do things like add this to my tests/behat/behat.yml file

        capabilities:
          browser: "chrome"
          version: "*"
          extra_capabilities:
            chromeOptions:
              w3c: false

But this didn't seem to work. I also added this to my docksal.yml file

      browser:
        hostname: browser
        # Pin selenium image to an older version
        # See https://github.com/docksal/docksal/issues/1096#issuecomment-543316840
        image: selenium/standalone-chrome-debug:3.141.59-oxygen
        dns:
          - ${DOCKSAL_DNS1}
          - ${DOCKSAL_DNS2}

I can see online that I should look at the D7 advanced boilerplate code for examples, but I am not sure which part of it is outdated.

What parts of D7 advanced boilerplate behat configs do I need to change if I am running Drupal 9?

Here is my behat.yml file: ( I am assuming that the base_url is the url I use in my browser when I look at the page )

        '': '%paths.base%/tests/behat/features/bootstrap'
