I'm trying to follow the WebDriverIo tutorial at http://webdriver.io/guide.html .
After setting up the Selenium server, when I try executing the test node script (step 7 in the tutorial), selenium warns me of some errors (see screenshot for full log), and I don't get any output returned.
Steps to reproduce:
When I try running the node script, this happens (clock to zoom):

At this point a Firefox window opens automatically, and remains blank.
I'm running Firefox v52 and Selenium 3.0.1. I downloaded Geckodriver from https://github.com/mozilla/geckodriver/releases
Any obvious thing that I'm missing? I'm very new to Selenium and browser automation, forgive the generic input :)
