SASS compiler failed with exit code 1 - nativescript

Question

I'm following the official getting started with NativeScript/Angular and working on this repo when I do tns run android I get the following:
Executing before-watch hook from /Projects/course-exercise-files-nativescript-angular-getting-started-guide/chapter2/02_07_end/Groceries/hooks/before-watch/nativescript-dev-sass.js
Found peer node-sass
No input file was found.
SASS compiler failed with exit code 1
My node version is: 10.15.1 on a Mac OS Mojave 10.14.2

You will see that error only when you don't have even one SCSS file in your project. Add at least one SCSS file to your project and the error should go away.
