Failed to open CheerpJ Global Bug Report #104

Closed oeway closed 4 years ago

Hi, sometimes I see cheerpj loader try to open a google docs window but failed due to CORS error, see below:

Access to XMLHttpRequest at 'https://docs.google.com/forms/d/e/1FAIpQLScErDRKZvSy1JAdiRSZfAsjf711VWdSdkczuSYHfIHQbtyFXA/formResponse' from origin 'https://ij.imjoy.io' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

This is not a real error, but just a side effect of our automatic bug report system. Something else is making your application crash before that.

This is documented here: https://github.com/leaningtech/cheerpj-meta/wiki/Frequently-Asked-Questions#my-application-compiled-with-cheerpj-does-not-work-and-i-see-a-cross-origin-error-to-a-google-service-in-the-console-whats-going-on
