Issue with Angular 6 route and Open vidu

  1. After integration open vidu works with site root. URL (https://sample-project-xtmqxq.stackblitz.io/)
  2. i have created component and want to integrate same component inside custom component but it does not work. (https://sample-project-xtmqxq.stackblitz.io/open-vidu)
  3. It shows lazy load console error
