I had the same issue. Just downloaded the latest release of chromedriver and that solved the problem.

Answer 2

update your protractor and run your test cases it will start executing, there are few new stuff added from Protractor, this method worked for me.

update protractor - npm install -g protractor update webdrvier - webdriver-manager update

Answer 3

With the last headless version, you can't resize the window as there isn't any window anymore.

For my own case, I was experiencing this issue with behat, I used to resize the window with previous versions of chrome of firefox, I surround the following line:

$this->getSession()->resizeWindow(1600, 1200, 'current');

with a simple check on the driver:

if (($this->getSession()->getDriver() instanceof Selenium2Driver)) {
    $this->getSession()->resizeWindow(1600, 1200, 'current');
}
