CesiumJS

Hey,

Ive seen people having same issue. Tileset doesnt appear by manualy going to it or it crashes during viewer.zoomTo, my code:

<!DOCTYPE html>
<html lang="en">
<head>
  <!-- Use correct character set. -->
  <meta charset="utf-8">
  <!-- Tell IE to use the latest, best version. -->
  <meta http-equiv="X-UA-Compatible" content="IE=edge">

  <script src="/RS/Build/Cesium/Cesium.js"></script>

  <style>
      @import url(/RS/Build/Cesium/Widgets/widgets.css);
      html, body, #cesiumContainer {
          width: 100%; height: 100%; margin: 0; padding: 0; overflow: hidden;
      }

      #measuretoolbar {
        position: absolute;
        top : 50%;
        right: 30px;
        display: inline;
        margin: 10px;
        padding: 0px;
        background: #394148;
      }
  </style>
</head>

<div id="cesiumContainer" class="fullSize"></div>

<div id="toolbar"></div>
  <script>
  Cesium.Ion.defaultAccessToken = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJqdGkiOiI0ZDhmZDlhYy0zOWIwLTQ5N2EtODEyYy00ODY1MzFkYzQwODUiLCJpZCI6MTg0MDMsInNjb3BlcyI6WyJhc3IiLCJnYyJdLCJpYXQiOjE1NzM3NTU0OTN9.vQn17q1cp77RAXXIjxv-IbfOkaiA2mP-QF8lmHo0XFk";

const viewer = new Cesium.Viewer("cesiumContainer", {

});
viewer.scene.globe.depthTestAgainstTerrain = true;

try {
  const tileset = viewer.scene.primitives.add(
  new Cesium.Cesium3DTileset({
    url: Cesium.IonResource.fromAssetId(2526103),
	skipLevelOfDetail : false,
   maximumScreenSpaceError:1,
   maximumNumberOfLoadedTiles :2000
  })
);
  viewer.scene.primitives.add(tileset);
 // viewer.zoomTo(tileset);

  // Apply the default style if it exists
  const extras = tileset.asset.extras;
  if (
    Cesium.defined(extras) &&
    Cesium.defined(extras.ion) &&
    Cesium.defined(extras.ion.defaultStyle)
  ) {
    tileset.style = new Cesium.Cesium3DTileStyle(extras.ion.defaultStyle);
  }
} catch (error) {
  console.log(error);
}
  </script>
</body'
</html>

is it because there is no terrain and height offset doesnt work? Happens only in this new Cesium, older I have doesnt have any problem.

Thanks
