Angular Datatables annoying error in alert

Question

I use this datatable for angular everyone uses. But i get this annoying error in an alert! Who does this?! I have to use dtTrigger, because of the HTML structure. Note, some text is in german. I get the clubs from RXJS with a selector. It's working, but i get this alert. How can i prevent this alert?! Can anyone help me here?

Anyway, here is the code:

HTML-File

<app-pagetitle title="Meine Clubs"></app-pagetitle>
<div class="currentClub" *ngIf="currentClub">
  <h3>{{ currentClub.title }}</h3>
  <p>{{ currentClub.maxloss }}</p>
</div>


<div class="row">
  <div class="col-12">
      <div class="card">
          <div class="card-header">
              <h4 class="card-title">Meine clubs</h4>
              <p class="card-title-desc">
                Hier findest du deine Clubs.
              </p>
          </div>
          <div class="card-body">
              <ng-container *ngIf="clubs$ | async as clubs">
                <table
                  datatable
                  [dtTrigger]="dtTrigger"
                  [dtOptions]="dtOptions"
                  class="row-border hover table-responsive table"
                  *ngIf="clubs?.length; else noClubs"
                >
                  <thead>
                    <tr>
                      <th>ID</th>
                      <th>Name</th>
                      <th>Actions</th>
                    </tr>
                  </thead>
                  <tbody>
                    <tr *ngFor="let club of clubs">
                      <td>{{club.uid}}</td>
                      <td>{{club.title}}</td>
                      <td>
                        <a [routerLink]="'/club/'+club.uid" class="btn btn-success">Anzeigen</a>
                        <button *ngIf="currentClub.uid !== club.uid" (click)="selectClub(club.uid)" class="btn btn-info">Auswählen</button>
                      </td>
                    </tr>
                  </tbody>
                </table>

                <ng-template #noClubs>
                  <p>Noch keine clubs vorhanden</p>
                </ng-template>
