Angular 7 “expected 'styles' to be an array of strings”

Question

I am trying to run my server and have my app.component.html load on localhost:8000. Instead, I am receiving this error

compiler.js:7992 Uncaught Error

Answer 1

Stylesheets which are referenced in your angular.json's styles[] cannot be referenced in a Component's styleUrls[] decorator.

Make sure that you are not referencing ./app.component.css in both files.
