WEB-38922 is fixed in 2019.1.3.
The issue is with ESLint version 6.x. If upgrading Webstorm is not an option for you, you have to downgrade to ESLint version 5:
npm install --save-dev eslint@5
Update: if you see similar error when working with ESLint 8, please make sure to upgrade to version 2021.2.2 where it’s supported (see WEB-52236)
