Hi, I'm using Google Gauge but sometimes I get CORS errors like the following one:

Access to XMLHttpRequest at 'https://www.gstatic.com/charts/51/css/core/tooltip.css' from origin 'https://sherlock.com.ar' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I attach the javascript file where you can find the code for the generation of the gauges, taking into account this. I've removed the extension to be able to attach the file.

Which could it be the problem? Is a bug in the libraries of the Google visualization charts?
