TypeError: fs.existsSync is not a function

While using Sass in a react project and using useRef hook, one might come across this error:

To solve this, simply look for

import {yourvarname} from "node-sass";

in the component where ref is being used and remove this line. Visual Studio Code automatically adds the line which causes the given error.
