TypeError: Cannot read properties of undefined (reading 'getBoundingClientRect')

Hello @e-oj, I really like your solution for the grid position
Unfortunately, a faced an issue with the implementation of your solution.

Could you please, support me with that?
Thanks in advance!

Here is my typescript code:

 this.taskService.getTasks().subscribe(
      response => {
        this.allTasks = response
        this.dates = Array.from(this.allTasks.keys()).sort();

        const magicGrid = new MagicGrid({
          container: '.tasks',
          items: 20,
          animate: true,
          gutter: 20,
          static: false
        });
        magicGrid.listen();
        magicGrid.positionItems();
      }
    )

My HTML code

<div class="tasks">
  <ng-container *ngIf="allTasks && allTasks.size > 0">
    <div *ngFor="let key of dates">
      {{key}}
    </div>
  </ng-container>
</div>
