npm ERR! JSON.parse Failed to parse package.json data ,error in creating npm light-server

Question

I was trying to run npm lite server ,but it is showing me "Failed to parse json data , I initiated the process with npm init command then I gave the command npm install lite-server --save-dev and it created the node module .after that I updated the script section as :

 "scripts": {
    "start":"npm run lite"
    "test": "echo \"Error: no test specified\" && exit 1"
    "lite":"lite-server"
  },

After that I gave the command npm start but then it creates an error Failed to parse json data which I do not know how to resolve . Following is the error log :

So can someone please suggest how to resolve this issue ,thank you!

Put your package.json file in a JSON [validator](https://jsonlint.com/) to see the errors. One issue is your each script commands should end with a `,` — Dilshan, Jun 18 '22 at 14:08

There should a comma , between every instruction in script section .

So the script section should be updated as :

"scripts": {
    "start":"npm run lite" ,
    "test": "echo \"Error: no test specified\" && exit 1" ,
    "lite":"lite-server"
  },
