Reproducible demo

The issue can be resolved by using a .eslintignore file. In my case is seems eslint was trying to lint the node_modules and adding a eslintignore file with just node_modules in it stop the error.

@Vanuan thank you, it fixed my problem!

So I changed my script from eslint . to estlint ./src and it now works like a charm. So I guess it was finding some *.ts file in any of the node modules or any other hidden folder that might have a ts file.
