WebGL Cardboard VR (GVR) errors

I am trying to build a scene using WebGL with Google GVR viewer script attached to my camera.

If I build without the GVR enabled my scene loads in browser, however with the GVR viewer enabled I am getting the following output:

An error occured running the Unity content on this page. See your browser JavaScript console for more info.
