repeated EJSONPARSE error - node.js

Question

"npm run react-dev" command gives this jsonparse error occurs repeatedly.
npm ERR! code EJSONPARSE
npm ERR! Failed to parse json
npm ERR! Unexpected token in JSON at position 595 while parsing ' {
npm ERR! "name": "reactnodetutorial",
npm ERR! "vers'
Tried the following but none worked.
1) deleted all directories and files and restarted this project from the scratch like building architecture and installing dependencies
2) deleted all contents in package.json file and copied the tutorial example's package.json contents which is perfect and pasted it to mine
3) update node and npm to the latest version
4) npm init and reinstall dependencies
5) npm cache clean --force
6) rm -f package-lock.json
How to possibly fix this.
