This error would seem to indicate that there is no element with an ID of "myHeading".

This can happen if the JavaScript code is executed before the page is fully loaded. Is the <script> tag the very last thing in the body of the HTML?

Close down the browser that has the console open and the work-space then re-fresh the tutorial page.

I had the same issue and did this and now it works.
