你好，为什么 scene.addS3MTilesLayerByScp 不能加载本地的 .scp 呢？

[quater23]

能加载：

• https://www.supermapol.com/realspace/services/3D-0523/rest/realspace/datas/Building_NoCBD_5huan_WebGL/config

不能加载：

• ./data/CBD/cbd.scp

加载代码：

 // let url = "https://www.supermapol.com/realspace/services/3D-0523/rest/realspace/datas/Building_NoCBD_5huan_WebGL/config";
      let url = "./data/CBD/cbd.scp";
      let promise = scene.addS3MTilesLayerByScp(url, { name: "cbd" });
      promise.then((layer) => {
        layer.readyPromise.promise.then(() => {
          scene.camera.setView({
            destination: layer.rectangle,
          });
          const _position = layer._position;
          viewer.scene.primitives.add(new Cesium.DebugModelMatrixPrimitive({
            modelMatrix: Cesium.Transforms.eastNorthUpToFixedFrame(_position),  // primitive to debug
            length: 1000.0,
            width: 4.0
          }));
        });
      });

请问这是为什么？在线地址也是请求的 .scp文件
