Loading Google Charts js throws exception on website but not on localhost

[SquarSwap]

I have an interesting problem with loading google charts. I can load the javascript without any issues when running my website on localhost, but when running on my production website the javascript fails to load.

The error message I get is from the call google.charts.load('current', {'packages':['corechart']});

This is the error:

uncaught exception: AssertionError: Failure: Argument is not a HTMLScriptElement (or a non-Element, non-Location mock); got: HTMLUnknownElement

You can see the error at https://squarswap.com/thumbsUp. I thought originally this may be an https issue, but I get the same error on http also.

Has anybody seen this error before? I'm not sure how to debug, I mostly work on backend so my js skills are not that great.

Thanks,

Thomas

Hi Thomas,

I don't fully understand what is going on yet, but it appears when the loader generates script tags to load the modules of the library, which is working fine in most cases, for some reason, your production environment is confusing the security context (or something at that level) enough that a 'script' tag generated by: goog.dom.createElement(goog.dom.TagName.SCRIPT);

does not appear to be an HTMLScriptElement as it should but instead ends up as a generic HTMLUnknonwElement. 

Why this is happening is a complete mystery to me, but perhaps if other people are seeing this too, we might begin to see a pattern.  I'll also ask some folks in Google who might be able to help.
