Hello,
Regarding the Workers/inflate error, how are you adding Cesium to your application? What does your <script> tag look like?
You should be using your own copy of Cesium, not linked to one on our website.
I don't think either of the errors are related to your visualization issue, however. Are you using a LatLonQuad? We don't have official support for this type yet, so that's why the image is turned.
Best,
Hannah
