GET scene.gltf 404 (Not Found)

Hi guys,
I tried everything what I found, but nothing happen.
Here is my GitHub code : GITHUB CODE

First error is

 GET http://127.0.0.1:5500/ThreeD/ThreeD/shiba/scene.gltf 404 (Not Found)
   ProgressEvent {isTrusted: true, lengthComputable: true, loaded: 169, total: 169, type: 'load', …}

and when I add back slash behind ThreeD here

loader.load( '/ThreeD/shiba/scene.gltf

got this

Uncaught (in promise) ReferenceError: scene is not defined
    at main.js:8:2
    at GLTFLoader.js:119:11
    at GLTFLoader.js:1178:9

do you know where is probably problem ?

this is not solution, if I remove that endpoint ThreeD, have same problem

for example without ThreeD when I use “/shiba/scene.gltf”

three.js:20044     GET http://127.0.0.1:5500/shiba/scene.gltf 404 (Not Found)
load @ three.js:20044
load @ GLTFLoader.js:116
(anonymous) @ main.js:6
main.js:12 ProgressEvent {isTrusted: true, lengthComputable: true, loaded: 155, total: 155, type: 'load', …}

I tried rewrite code to

const loader = new GLTFLoader();
var scene = new THREE.Scene();
loader.load( 'shiba/scene.gltf', function ( gltf ) {

	scene.add( gltf.scene );

}, undefined, function ( error ) {

	console.error( error );

} );

add scene because wasn’t defined,now I don’t have any error, but nothing appear on my screen.

I fix this solution by this code
anyway, always I have to add camera background screen and render ?

import * as THREE from 'https://cdn.skypack.dev/three@0.129.0/build/three.module.js';
import { GLTFLoader } from 'https://cdn.skypack.dev/three@0.129.0/examples/jsm/loaders/GLTFLoader.js';

const loader = new GLTFLoader();
var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera( 25, window.innerWidth / window.innerHeight, 1, 20000 );
camera.position.set( 1, 1, 20 );
var renderer = new THREE.WebGLRenderer({ alpha: false });
renderer.setClearColor( 0xC5C5C3 );
renderer.setPixelRatio( window.devicePixelRatio );
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

loader.load( 'shiba/scene.gltf', function ( gltf ) {
	gltf.scene.scale.set( 1, 1, 1 );			   
	gltf.scene.position.x = 0;				    //Position (x = right+ left-) 
    gltf.scene.position.y = 0;				    //Position (y = up+, down-)
	gltf.scene.position.z = 0;		
	scene.add( gltf.scene );
	
	


}, undefined, function ( error ) {

	console.error( error );

} );

function animate() {
	render();
	requestAnimationFrame( animate );
	}

function render() {
	renderer.render( scene, camera );
	}

render();
animate();

that is easy to test - do not add it, and observe the result - if it turns out not the way you wanted it - then yes, you had to add it.

yap, anyway thanks @makc3d
