I tried to 'Augmented Reality in 10 Lines of HTML'. But this is not working.

If the current behavior is a bug, please provide the steps to reproduce.

1. npm ar.js to my local or see a codepen
   https://github.com/jeromeetienne/AR.js#augmented-reality-for-the-web-in-less-than-10-lines-of-html
2. run(local, codepen)
3. Don't show 3d model on marker and show error message
   
4. But it's working.
   https://jeromeetienne.github.io/AR.js/three.js/examples/mobile-performance.html

What is the expected behavior?
Show 3d model on marker

If this is a feature request, what is motivation or use case for changing the behavior?

I think it's a problem with your error in GET camera-para.dat ;)

Also you can do it offline by copying the node_modules folder to wwwroot (im using asp.net core)
and adding:

<script src="~/js/aframe.min.js"></script> 
<script src="~/js/aframe-ar.js"></script>

<script>
    THREEx.ArToolkitContext.baseURL = '/node_modules/ar.js/three.js/'
</script>
