sometimes $results['value']['ELEMENT'] is not defined inside WebDriver.php line 368

[ghost]

added this line

if (!isset($results['value']['ELEMENT'])) throw new SeleniumNoSuchElementException();

I dunno if thats the best error to throw, but its better than leaving it completely unhandled and getting notices.

return new WebElement($this, $results['value']['ELEMENT']);#just showing this line for reference

Ran into the same issue, but instead used

return isset($results['value']['ELEMENT']) ? new WebElement($this, $results['value']['ELEMENT']) : null;

The function is be triggered by waitForElementUntilIsPresent() when used By::id(), so throwing a exception isn't the best solution imo.
