Current behavior

Hello all.

I'm trying to set up Wallaby Selenium in GitHub Actions. Before moving to GH Actions I want to make this work locally. But it doesn't initiate a new session. Probably it's my local problem but I found one questionable moment.

Here is my Wallaby configuration

config :wallaby,
  otp_app: :codemetrics_el,
  driver: Wallaby.Selenium,
  selenium: [
    capabilities: %{
      javascriptEnabled: true,
      browserName: "chrome",
      chromeOptions: %{
        args: [
          "--no-sandbox",
          "window-size=1280,800",
          "--disable-gpu",
          "--headless",
          "--fullscreen",
        ]
      }
    }
  ],
  screenshot_dir: "tmp/wallaby_screenshots",
  screenshot_on_failure: true

And I start Chrome in Selenium Grid this way

docker run --rm -e SE_NODE_MAX_SESSIONS=8 -e SE_NODE_OVERRIDE_MAX_SESSIONS=true --shm-size="2g" -p 4444:4444 -p 5900:5900 -p 7900:7900 selenium/standalone-chrome:latest

When I start tests, I see Wallaby's requests to Selenium with the following parameters.

"http://localhost:4444/wd/hub/session"
"{\"desiredCapabilities\":{\"browserName\":\"chrome\",\"chromeOptions\":{\"args\":[\"--no-sandbox\",\"window-size=1280,800\",\"--disable-gpu\",\"--headless\",\"--fullscreen\"]},\"javascriptEnabled\":true}}"

When the Selenium Grid, I see these requests like with an empty list of desired capabilities

It ends up with a timeout request for a session.

Expected behaviour

It looks weird that list of capabilities is empty In Selenium Grid. My guess is since capabilities (particularly browserName parameter) are empty, Selenium Grid doesn't know what type of a session should be created.

Test Code & HTML

All test data provided in the "Current behaviour" section.

I made it work with Chrome 103, but it doesn't work at least in 114.
