A issue of creating a virtual Earth

Hello everyone, my project is currently upgrading to Cesium 1.118, but I encountered an issue while creating a virtual Earth. This is the error message it displays:
Uncaught (in promise) SyntaxError: Unexpected token '<', "<!DOCTYPE "... is not valid JSON at JSON.parse (<anonymous>) at Resource.js:1183:17
It seems to be associated with these code in Resource.js:
return promise.then(function (value) {
if (!defined(value)) {
return;
}
return JSON.parse(value);
});
How could this happened? How I can fix it?

Hi there,

I think we’ll need more information to track down the issue. Do you have a code example that replicates the issue?

If not, could you explain your app configuration?
