在vue2环境下引入kml中的模型gltf文件失败报错

使用产品：SuperMap iClient3D for Cesium 操作系统：win10 x64
文件类型： kml与gltf文件
问题详细描述：参考官网http://support.supermap.com.cn/DataWarehouse/WebDocHelp/iServer/webgl/examples/webgl/editor.html#KML_car小车移动示例，引入kml文件，在kml文件中的模型加载失败，报错，前端环境为vue2，资源放在public静态文件夹下，代码如下：

 let kmlUrl = "../../../public/static/kml/model.kml";
      let kmlDataPromise = Cesium.KmlDataSource.load(kmlUrl, {
        camera: window.viewer.scene.camera,
        canvas: window.viewer.scene.canvas,
      });

      kmlDataPromise.then((dataSource)=>{
        console.log(dataSource,'dataSource')
        console.log(dataSource.entities.values[0],'dataSource.entities.values[0]')
        window.viewer.dataSources.add(dataSource);
        var entity = dataSource.entities.values[0];
          if(entity.path){
              entity.path.show = false;
          }
      })

代码log中dataSource.entities.values[0]没有值

kml文件如下

gltf文件路径应该是没有问题的

报错如下

请问有没有遇到同样问题的大佬帮我看看，是啥原因导致的？
