Hello. I’m a researcher from South Korea.

I’m using Cesium js. and i’m planning to use cesium-terrain-server.
Because I have fine DEM of South Korea.

so I installed Go language, and pull git in my server.

Terrain data was made by ctb-tiles(Cesium Terrain Builder).

But in Cesiumjs, i failed to load data.

var terrainProvider = new Cesium.CesiumTerrainProvider({
  url: 'http://URL:PORT/customTileset/',
});

viewer.scene.terrainProvider = terrainProvider;

It doesn’t even import the layer.json file.
I checked Chrome dev mode in network tab.

I can reach with browser. it means server and ports are fine.
I can even check the file with the browser.
