Hi @kumaresan-subramani! Per this repository's README, tslint-to-eslint-config requires Node >=10. You're running Node 8. Please update your version of Node. Given that both npx eslint --init and npx tslint-to-eslint-config are giving you the same Path must be a string. Received undefined error, I doubt the issues you're facing are unique to tslint-to-eslint-config.

Closing this issue for housekeeping, but if you update to Node >=10 (I recommend the latest versions, 14 or 15), and the issue persists, please do feel free to post here again and we can take another look. Thanks!

The main issue I see is the lack of tslint.json file on the repository, which is required to perform the migration to ESLint 🧐
