cesiumlab的3Dtiles加载问题

同样的代码在cesium的Sandcastle中可以run 但是用vscode运行后就不会出现3Dtiles 报错说无法加载 Failed to load resource: net::ERR_INCOMPLETE_CHUNKED_ENCODING [http://localhost:9002/api/folder/f72f1675c263469e83eb2680b6db8b09/tileset.json?v=0.0] A 3D tile failed to load: http://localhost:9002/api/folder/f72f1675c263469e83eb2680b6db8b09/tileset.json?v=0.0 Cesium.js:514 Error: Request has failed. 最后浏览器还崩溃了
