I have an angular 6 application. I am trying to load users from a backend. Here is my component typescript part:

 this.users$ = this.userSearchControl

  .valueChanges

  .debounceTime(200)

  .filter(q => q && q.length > 5)

  .switchMap(q => this.getUsers(q))

  .share();

And template part:

<div *ngIf="(users$ | async) as users" class="results">



  <ul class="list">

    <li *ngIf="users.length===0">

      <div class="no-results">

        <span>No orders found</span>

      </div>

    </li>

    <li *ngFor="let user of users" class="list-item">

      {{user.Name}}

    </li>

  </ul>

</div>

And I am getting an exception:

ExpressionChangedAfterItHasBeenCheckedError: Expression has changed after it was checked. Previous value: 'ngIf: false'. Current value: 'ngIf: true'.

I have tried to play around ChangeTracker, and delay(0) but no success. Thanks for any assistance
