ngFor not showing data Ionic 4

Issue

I tried to loop my data in *ngFor but it's not showing data but in my console, it's showing. Below is my code that I tried.

api.service.ts

    getOrder(orderId): Observable<CustomerOrder> {
       return this.http
      .get<CustomerOrder>(this.apiUrl + 'OrderProduct/' + orderId)
      .pipe(
        retry(2),
        catchError(this.handleError)
      )
  }

orderdetails.component.ts

orderData: any[] = [];

ngOnInit() {
   this.orderId = this.activatedRoute.snapshot.params.orderId;
   this.apiService.getOrder(this.orderId).subscribe(res => {
  Object.assign(this.orderData, res);
  console.log(res);
});
}

orderdetails.page.html

<ion-card *ngFor="let ord of orderData">
      <ion-card-title>
        <h4 class="ion-text-center" style="font-weight: bold">{{ord.Customer?.Name}}</h4>
        <h5 class="ion-text-center">{{ord.OrderNo}}</h5>
      </ion-card-title>
      <ion-card-content>
       <ion-list>
          <ion-item>
            <p style="font-weight: bold">Items: </p>&nbsp;
            <ion-label>{{ord.OrderProducts?.Product}}</ion-label>
          </ion-item>
          <ion-item>
            <p style="font-weight: bold">Quantity: </p>&nbsp;
            <ion-label>{{ord.Quantity}}</ion-label>
          </ion-item>
          <ion-item>
            <p style="font-weight: bold">Item Price: </p>&nbsp;
            <ion-label>{{ord.ItemPrice}}</ion-label>
          </ion-item>
        </ion-list>
       </ion-card-content>
      <ion-button type="button" color="primary"
                  style="float: right; padding-right: 5px;padding-bottom: 3px;" 
        (click)="closeOrder()">
        Close
      </ion-button>
      <ion-button type="button" color="danger"
                  style="float: left; padding-left: 5px;padding-bottom: 3px;">
        Cancel
      </ion-button>

    </ion-card>

In console it's showing data below it is

Solution

I fixed it. In the ts file, I wrapped data like this.

 this.apiService.getOrder(this.orderId).subscribe(res => {
  this.orderData = [res];
   console.log(res);
});
