Observable.of is not a function
If anybody is having this problem while using Angular >= 6 and rxjs version 6 or greater, see the answers here:Could not use Observable.of in RxJs 6 and Angular 6
In short, you need to import it like this:
import { of } from 'rxjs';And then instead of calling
Observable.of(res);just use
of(res);
Although it sounds absolutely strange, with me it mattered to capitalize the 'O' in the import path of import {Observable} from 'rxjs/Observable. The error message with observable_1.Observable.of is not a function stays present if I import the Observable from rxjs/observable. Strange but I hope it helps others.
