CesiumJS:3Dtiles tileset path ? (windows)

Good morning,
I’m trying to load and display my 3D tiles file with CesiumJS on my windows station and chrome web browser.
Cesium server seems to running fine locally. When i type the 'npm start’command via one windows prompt command, it appears :

> >node server.cjs
> *Cesium development server running locally.  Connect to http://localhost:8080/*

Indeed, browse to http://localhost:8080/ is displaying well.
But i have a problem in order to read with Cesium my 3Dtiles tileset.
In another windows prompt command, i type this following command :

*C:\Users\lcelati>python -m http.server*
*Serving HTTP on :: port 8000 (http://[::]:8000/)* 

I paste below my sancastle javascript :

> var viewer = new Cesium.Viewer("cesiumContainer", {
> });
> var tileset = new Cesium.Cesium3DTileset({
>   url: 'http://localhost/3D-Tiles/tileset.json'
> });
> viewer.scene.primitives.add(tileset);
> tileset.readyPromise.then(function (tileset) {
>   viewer.scene.camera.setView({
>     destination: tileset.root.boundingVolume.rectangle,
>   });
> });

When i run the code, nothing appears with no error message within the console.
According to me, the problem would be come from my tileset path. Could you tell me where i should store my 3Dtiles dataset ? Within my python path? Cesium path?
Should i add some lines within my javascript sancastle file regarding the python server ?

In advance, thanks a lot for your usefull help.
With kind regards.

If you open http://localhost/3D-Tiles/tileset.json in the browser, does it load the JSON file? If not, you need to make sure you have your local server set up so that you can access the 3D Tileset as static files.

You can also upload your 3D Tileset to Cesium ion (https://cesium.com/ion) to host it that way.

Thanks for your reply. But when i’m trying to open http://localhost/3D-Tiles/tileset.json , it does not work. I have installed nodejs and for the http server, up to now i have no install apache. I’m using this following python command : “python -m http.server”. Do you know where i have to execute this python command ? (in root cesium folder?Elsewhere?). Is it possible to use this “python http serving” way or i’m obliged to install apache webserver? )
I just make a test with Cesium-ion. The data file name seems to be appeared in the list but when i make a zoom on the data footprint, i can’t display the data.
