Visual Studios Code "cannot read properties of null (reading 'width') "

I am brand new to JavaScript, just started today. Trying to pick up on the basics watching a YouTube video and I get this error that pops up when I try “JS Repl: Run”

Does anyone know how to fix this issue I am having reading ‘width’?

I have included a screen shot of the error and the files I currently have setup
(excluding | .gitignore | .vscode | package.json | package-lock.json | node_mdules(folder*) | OrbitControls.js | favicon.svg |).

At the end of this question I have another screen shot of multiple package.json’s and package-lock.json’s and wondering if I accidentally duplicated those and if I need to delete from one file location or the other.

renderer.render(scene, camera)

const pointLight = new THREE.PointLight(0xffffff)

pointLight.position.set(20, 20, 20)

const ambientLight = new THREE.AmbientLight(0xffffff)

scene.add(pointLight, ambientLight)

//const controls = new OrbitControls(camera, renderer.domElement)

function addStar(){

  const geometry = new THREE.SphereGeometry(0.25, 24, 24)

  const material = new THREE.MeshStandardMaterial({color: 0xffffff})

  const star = new THREE.Mesh(geometry, material)

  const [x, y, z] = Array(3).fill().map(() => THREE.MathUtils.randFloatSpread(100))

  star.position.set(x, y, z)



const spaceTexture = new THREE.TextureLoader().load('./images/spaceImage.png')

scene.background = spaceTexture

function animate(){


  torus.rotation.x += 0.01

  torus.rotation.y += 0.005

  torus.rotation.z += 0.01

  renderer.render(scene, camera)





this how I have my code in javascript and Typescript proyects



<canvas class="webgl"></canvas>


// Canvas
const canvas = document.querySelector('canvas.webgl');
 * Renderer
const renderer = new THREE.WebGLRenderer({
    canvas: canvas
renderer.setSize(sizes.width, sizes.height)
renderer.setPixelRatio(Math.min(window.devicePixelRatio, 2))

for typescript I put both. I dont know. Maybe it also work for you

  <div #canvas id="canvas"> </div>

unfortunately width still equals null. Can I set the width value somewhere before THREE.WebGLRenderer or maybe in .html or .css?

I see you are using THREE.WebGL1Renderer. Can you change it to THREE.WebGLRenderer and see if works?

@GhostRider could you push your code to GitHub?
