Angular GetCookie Method from SO does not work anymore

I have the following code from SO:

import { Injectable } from '@angular/core';

@Injectable()
export class CookieService {


  constructor() { }

  public getCookie(name: string) {
    const ca: Array<string> = document.cookie.split(';');
    const caLen: number = ca.length;
    const cookieName = `${name}=`;
    let c: string;

    for (let i = 0; i < caLen; i += 1) {
      c = ca[i].replace(/^\s+/g, '');
      if (c.indexOf(cookieName) === 0) {
        return c.substring(cookieName.length, c.length);
      }
    }
    return '';
  }

  public deleteCookie(name: string) {
    this.setCookie(name, '', -1);
  }
  /**
   * Expires default 1 day
   * If params.session is set and true expires is not added
   * If params.path is not set or value is not greater than 0 its default value will be root "/"
   * Secure flag can be activated only with https implemented
   * Examples of usage:
   * {service instance}.setCookie({name:'token',value:'abcd12345', session:true }); <- This cookie will not expire
   * {service instance}.setCookie({name:'userName',value:'John Doe', secure:true }); <- If page is not https then secure will not apply
   * {service instance}.setCookie({name:'niceCar', value:'red', expireDays:10 }); <- For all this examples if path is not provided default will be root
   */

  public setCookie(name: string, value: string, expireDays: number, path: string = '') {
    const d: Date = new Date();
    d.setTime(d.getTime() + expireDays * 24 * 60 * 60 * 1000);
    const expires: string = 'expires=' + d.toUTCString();
    document.cookie = name + '=' + value + '; ' + expires + (path.length > 0 ? '; path=' + path : '');
  }
}

When I try to console.log(this.CookieService.getCookie('cookienamehere'); the cookie does not get displayed and an empty string gets printed out instead... What happened? It used to work... The code has been mildly corrected to contain const and etc as you can see in the code.
