Selenium invalid argument

I'm trying to set up codeception.

When running any acceptance tests i get the following error:

> 1) FirstCest: Test
 Test  tests\acceptance\FirstCest.php:tryToTest

  [Facebook\WebDriver\Exception\InvalidArgumentException] invalid argument
  (Session info: chrome=81.0.4044.92)


Scenario Steps:

 1. $I->amOnPage("/") at tests\acceptance\FirstCest.php:14

Here is my config:

class_name: AcceptanceTester
colors: true
modules: 
    enabled:
        - WebDriver
        - Asserts
        - \Helper\Acceptance
    config:
        WebDriver:
            url: 'www.google.com'
            browser: 'chrome'
            window_size: 1280x1280
            wait: 10

Im running chrome 81.

and I start my selenium-standalone server like so

java -jar .\selenium-server-standalone-3.141.59.jar

What argument am I mmissing ?

Thank you.
