When I first run this example I can get it to work but if refresh the page I get the following error:

TypeError: Cannot assign to read only property '1' of [object Array]

It also works if I change the file and re-save it. If I refresh after that it stops working again.

I have set my graph.cool end point in initClient.js. Is there something I am not doing correctly?
