if you read the code it returns the this.previousUrl = this.currentUrl. I think its great if people spent time and contribute to community, but they should make sure what they post its valid.

Here is the revised code which works at least for me

import { Injectable } from '@angular/core';
import { Router, NavigationEnd, RoutesRecognized } from '@angular/router';
import {filter, pairwise } from 'rxjs/operators';

@Injectable()
export class PreviousRouteService {

 private previousUrl: string;

 constructor(private router: Router) {

this.router.events
  .pipe(filter((evt: any) => evt instanceof RoutesRecognized), pairwise())
  .subscribe((events: RoutesRecognized[]) => {
    this.previousUrl = events[0].urlAfterRedirects;
    console.log('previous url', this.previousUrl);
  });
 }
 public getPreviousUrl() {
  return this.previousUrl;
 }
 }
