WebGL Context "TypeError: Illegal invocation"

[Stuart B]

Hello,

I am trying to run the example webgl page here: https://github.com/skulpt/skulpt/blob/master/example/webgl/webgl-0001-basic.html

I have modified the scripts from:

<script src="../../dist/skulpt.js" type="text/javascript"></script>

<script src="../../dist/builtin.js" type="text/javascript"></script>

To:

<script src="http://www.skulpt.org/static/skulpt.js" type="text/javascript"></script> 

<script src="http://www.skulpt.org/static/builtin.js" type="text/javascript"></script>

But everything else is identical.

When I try to run the code, it fails on the second python line:

gl = webgl.Context("my-canvas")

And returns the error: "TypeError: Illegal invocation"

Could anyone please help identify what I am doing wrong? I see that this example is quite old, so maybe it's no longer compatible.

Thanks,

Stuart

Update...

So, I have found out that this example does indeed work as expected if I open it in Safari. It just doesn't seem to work in Chrome.

I have tried to search for this, but am struggling to understand. If anyone can suggest why this might be, I would be very grateful to hear it.

Thanks,

Stuart
