Angular 6 Component Require JSON ExpressionChangedAfterItHasBeenCheckedError

Problem:

In an Angular 6 project, a simple component that gets json data from a local file generates error: ExpressionChangedAfterItHasBeenCheckedError

Solution:

Do not use the following method to import local json data into the component:
const data = require('./data.json');

Use other standard approaches e.g.

this.http.get(this.dataUrl).subscribe((data: any) => {
// Do something with json data!
});
