Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'length') for vertices of three.js

So I'm converting an html project to a laravel/vue project. The html file had a three.min.js file which I can not figure out the version of. And some custom script files.

I've imported all of them for my vue component. I ran into different errors for the three.min.js file, so I npm installed version r69 of three.js becauseI read in recent versions, the geometry had changed. One of the custom files, test.js is using three.js. And I am running into the following error in my console.log

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'length') at test.js?t=1674045010699:37:39

test.js file code:

import * as THREE from "three";

// import ('../../assets/js/three.min.js')
// import "../js/anime.js"
// import "../js/three.js"

var canvas = document.querySelector("#scene");
var width = canvas.offsetWidth,
    height = canvas.offsetHeight;
var renderer = new THREE.WebGLRenderer({
    canvas: canvas,
    antialias: true,
});
renderer.setPixelRatio(window.devicePixelRatio > 1 ? 2 : 1);
renderer.setSize(width, height);
renderer.setClearColor(0x161d31);
var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera(100, width / height, 0.1, 10000);
camera.position.set(120, 0, 300);
var light = new THREE.HemisphereLight(0xffffff, 0x0c056d, 0.6);
scene.add(light);
var light = new THREE.DirectionalLight(0x590d82, 0.5);
light.position.set(100, 300, 400);
scene.add(light);
var light2 = light.clone();
light2.position.set(-100, 300, 400);
scene.add(light2);

var material = new THREE.MeshPhongMaterial({
    emissive: 0x23f660,
    emissiveIntensity: 0.4,
    shininess: 0,
});

var geometry = new THREE.IcosahedronGeometry(120, 4);

for (var i = 0; i < geometry.vertices.length; i++) {
    var vector = geometry.vertices[i];
    vector._o = vector.clone();
}

var shape = new THREE.Mesh(geometry, material);
scene.add(shape);

function updateVertices(a) {
    for (var i = 0; i < geometry.vertices.length; i++) {
        var vector = geometry.vertices[i];
        vector.copy(vector._o);
        var perlin = noise.simplex3(
            vector.x * 0.006 + a * 0.0002,
            vector.y * 0.006 + a * 0.0003,
            vector.z * 0.006
        );
        var ratio = perlin * 0.4 * (mouse.y + 0.3) + 0.9;
        vector.multiplyScalar(ratio);
    }
    geometry.verticesNeedUpdate = true;
}

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

function onResize() {
    canvas.style.width = "";
    canvas.style.height = "";
    width = canvas.offsetWidth;
    height = canvas.offsetHeight;
    camera.aspect = width / height;
    camera.updateProjectionMatrix();
    renderer.setSize(width, height);
}

var mouse = new THREE.Vector2(0.8, 0.5);
function onMouseMove(e) {
    TweenMax.to(mouse, 0.8, {
        y: e.clientY / height,
        x: e.clientX / width,
        ease: Power1.easeOut,
    });
}

requestAnimationFrame(render);
window.addEventListener("mousemove", onMouseMove);
var resizeTm;
window.addEventListener("resize", function () {
    resizeTm = clearTimeout(resizeTm);
    resizeTm = setTimeout(onResize, 200);
});

I don't know anything about three.js, my main task here is to convert the entire project into vue/laravel so I have other things to worry about. Does anyone know how to resolve this?

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...

How to show number of registered users in Laravel based on usertype?

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE".
