Node.js Cannot Find Module error on npm start - node.js

Question

I am getting an error like the below when I run npm start command to start the server for my first react project. I have tried uninstalling and reinstalling the node.js but did not work. How can I resolve this issue? I am including my package.json and my directory structure over here.
This is the error:
> reactproject1#1.0.0 start C:\Users\LENOVO\reactproject1
> node index.js
internal/modules/cjs/loader.js:969
throw err;
^

This is my package.json file of my react project. I have edited it by adding "start":"node index.js".
{
"name": "reactproject1",
"version": "1.0.0",
"description": "restropart",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "node index.js"
},
"author": "",
"license": "ISC",
"dependencies": {
"react": "^16.13.1",
"react-dom": "^16.13.1"
}
}
My Directory tree is as follows
-ReactProject
-node_modules
-public
-src
->index.js
-package.json
-package-lock.json
My index.js file resides inside the src folder. The node_modules, public, src, package.json and package-lock.json files are on the same line.

The start script refers to index.js, but you don't have such a file - it's under src/index.js. You could either move it to the project root, or update the start script accordingly:
"scripts": {
"start": "node src/index.js"
},
