Angular 6: Property 'catch' does not exist on type 'Observable'?

Question

I am upgrading my app to Angular 6. I am upgrading from Angular 4, but the code below is causing errors in Angular 6, where it worked fine

Answer 1

Import the Library with following method and rearrange the code

import { catchError } from 'rxjs/operators';
return Observable.pipe(catchError =>...);

This worked for me.
