Struggling to create a cube in THREE.js using BufferGeometry, but encountering issues with the image not loading correctly. Despite trying various solutions, it seems that the uv coordinates are not functioning as expected.

//Load the canvas to draw on
var canvas = document.querySelector('#canvas')
// The three.js scene: the 3D world where you put objects
const scene = new THREE.Scene();
function degrees_to_radians(degrees) {
let pi = Math.PI;
return degrees * (pi / 180);
}
// The camera
const camera = new THREE.PerspectiveCamera(
60,
window.innerWidth / window.innerHeight,
0.0001,
10000
);
// The renderer: something that draws 3D objects onto the canvas
const renderer = new THREE.WebGLRenderer({ canvas: canvas });
renderer.setSize(window.innerWidth, window.innerHeight);
renderer.setClearColor(0x4a4a4a, 1);
document.body.appendChild(renderer.domElement);
const controls = new THREE.PointerLockControls(camera, document.body);
document.addEventListener('click', function () {
controls.lock();
});
var key_map = {}; // You could also use an array
onkeydown = onkeyup = function (e) {
e = e || event; // to deal with IE

Encountering an odd issue where the texture fails to load properly.
