InvalidArgumentException When using Selenoid WebDriver.Remote

Question

I'm trying to setup my selenium test suite to use Firefox, I'm using selenoid to dockorize the browser for testing. From my understanding I'm doing everything correctly but I'm getting an InvalidArgumentException.

Here is where I'm defining the webdriver.Remote:

firefox_caps = {
  "browserName": "firefox",
  "browserVersion": "97.0",
  "selenoid:options": {
    "enableVNC": True,
    "enableVideo": False
  }
}
cls.driver = webdriver.Remote(command_executor="http://localhost:4444/wd/hub", desired_capabilities=firefox_caps)

And here is the contents of my browsers.json file that selenoid is using:

{
        "chrome": {
                "default": "88.0",
                "versions": {
                        "88.0": {
                                "image": "selenoid/vnc_chrome:88.0",
                                "port": "4444",
                                "path": "/",
                                "env": ["TZ=America/Denver"]
                        }
                }
        },
        "firefox": {
                "default": "97.0",
                "versions": {
                        "97.0": {
                                "image": "selenoid/vnc_firefox:97.0",
                                "port": "4444",
                                "path": "/"}
                }
        }
}

Here is the error message I'm getting when I star the tests:

Answer 1

For Firefox images path should be /wd/hub.
