Globe does not work with json import

Good morning, I have been writing a cesium.js code in which I want to import some points (json) with their latitude, length and height, and when I run the program the earth model is not seen
this is the code. If anyone knows please I would appreciate it because I don’t see where the error is.

Cesium Points Example #cesiumContainer { width: 100%; height: 90vh; margin: 0; padding: 0; overflow: hidden; } #loadButton, #fileInput, #colorFilter, #measureButton { position: absolute; top: 10px; left: 10px; z-index: 1; } #fileInput { display: none; } #colorFilter { top: 50px; } #measureButton { top: 90px; }
