When I upload the 3dtile to Cesium, I need to wait for the tileset to finish loading before I can move the camera to the model, my method is as follows：

tileset.await.then(function (tileset) {  
viewer.zoomTo(tileset);  
}).catch(function (error) {  
console.error('Error: ', error);  
});

but problem is that Uncaught TypeError: Cannot read properties of undefined (reading ‘then’)

Who was able to give the correct code, thanks

Hi,

Welcome to the Cesium community @peng_chen

You can find an example of how to load and view data in ion by going to the _View complete code example_ link in the asset details panel. Here is an example of viewing a 3D tileset asset.

```js
const tileset = await Cesium.Cesium3DTileset.fromIonAssetId(<insert your id here>);
viewer.scene.primitives.add(tileset);
await viewer.zoomTo(tileset);

```
