Unsupported locator strategy: null

[sabf]

Hello here!

since chromedriver 76 we get this exception in one of our tests:

org.openqa.selenium.InvalidArgumentException: invalid argument: Unsupported locator strategy: null

  (Session info: chrome=80.0.3987.87)

Build info: version: '3.141.59', revision: 'e82be7d358', time: '2018-11-14T08:17:03'

Is there any known bug?

We wait for an text by javascript on a page, where a canvas game is open in an iframe, developed with the Impact.js-Framework https://impactjs.com/

new WebDriverWait(driver, 60).pollingEvery(Duration.ofSeconds(5)).until((ExpectedCondition<Boolean>) webDriver ->
        HTML5TestBase.getJavaScriptExecutor().executeScript("return window.top.parent.document.getElementById('crossWindowMessageContainer').textContent").toString().contains("gameLoadingEnded"));

The same error occur if we try it with this command:

driver.findElement(By.cssSelector("#desktopGameMenu"));

Environment:

chromedriver: 80.0.3987.16

selenium-server-standalone: 3.141.59
Selenium-Grid

Thanks
