I am Trying to load gltfLoader at node js server side but i will give that error.
if i will run script in browser then it will working fine but not at server side

 global.XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
 global.THREE = require('/home/visilean/Ravi/HoungCode/threebim/js/libsCore/three');
 const GLTFLoader = require('/home/visilean/Ravi/HoungCode/threebim/js/libs/loaders/GLTFLoader.js');
 const loader = new THREE.GLTFLoader();
 
 loader.load(
     'http://localhost:8080/download?token=02b7ed8fabb84e987ac2cb40c0538d2352f6f8a630bdde708ec8ea1d9db3d0d289e9b97658c07acaa3146c8a72a6acc0&serializerOid=1572902&topicId=1',
     ( gltf ) => {
         // called when the resource is loaded
         scene.add( gltf.scene );
     },
   ( xhr ) => {
        // called while loading is progressing
         console.log( `${( xhr.loaded / xhr.total * 100 )}% loaded` );
     },
     ( error ) => {
       
         console.error( 'An error happened', error );
     },
 );

i will getting that below error.

I don’t think this is a three.js related issue. If JSON.parse() produces a runtime error, there is something wrong with the emulated XHR request on node.js.

any alternate way to run GLTFLoader at node js back end side intends browser ?

Read this topic for more information. It seems loading a glb makes the usage in context of node.js easier:
