Three.js - Uncaught ReferenceError: i is not defined-CodePudding

I'm working on a three.js project using parcel bundler.

Everything is working perfectly in my local system. But when I try to deploy it on Netlify, I get the following error:

Uncaught ReferenceError: i is not defined at app.js:45:16

The code in app.js at 45 is:

/*41*/  const particlesGeo = new THREE.BufferGeometry();
/*42*/  const particlesMat = new THREE.PointsMaterial({
/*43*/    size: 0.01,
/*44*/    map: loader.load(sparkleTexture),
/*45*/    transparent: true,
/*46*/  });

I tried different platforms for the deployment and surge is working perfectly. What could be the problem here on netlify?

Netlify build settings:

package.json:

{
  "name": "particle-system",
  "version": "1.0.0",
  "description": "",
  "source": "src/index.html", // Added due to parcel error in netlify production
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "gsap": "^3.11.3",
    "parcel": "^2.7.0",
    "three": "^0.145.0"
  }
}

You have this line in your app.js file:

for (i = 0; i < particlesCount * 3; i  ) {

The runtime error occurs since i is not defined. Changed the code to:

for (let i = 0; i < particlesCount * 3; i  ) {
