Sorry for the inconvenience.

We want to inform you that the repository is using Gulp 3 which is not supported in latest version of Node.js setup. We request you to follow the below steps to fix this issue.

1. Clone/download and extract the repository
2. Run the “npm install” command
3. Then, change the package.json as below
   ` "scripts": {
   "start": "gulp start",
   "serve": "gulp e2e-serve",
   "test": "gulp e2e-test",
   "build": "webpack --mode production",
   "update-webdriver": "gulp e2e-webdriver-update",
   "preinstall": "npx npm-force-resolutions"
   },
   "resolutions": {
   "graceful-fs": "^4.2.4"
   }

`
4. Again, run “npm install” command
5. Now, running “npm run start” will work.
