角度9材质v9错误RangeError：超出最大调用堆栈大小

如何解决角度9材质v9错误RangeError：超出最大调用堆栈大小

我正在使用Angular 9上的自定义验证器-

我想做的是，我正在验证信用卡，如果无效，请设置自定义验证消息，如果有效，则删除验证消息。很简单。

HTML-

<form [formGroup]="paymentAccountDetails" class="create-form">
   <mat-grid-tile>
          <mat-form-field class="width-80-percent">
            <input matInput placeholder="Card Number" pattern="[0-9]{4}\s[0-9]{4}\s[0-9]{4}\s[0-9]{4}\s[0-9]{4}\s" maxlength="20" formControlName="cardNumber" (ngModelChange)="myCardChange($event)" [ngModel]="cardNumber">
            <!-- <mat-error *ngIf="!isCardValid">
              Invalid card number 1
            </mat-error> -->
            <mat-error *ngIf="paymentAccountDetails.get('cardNumber').errors.AllTypeCardValidator">
              Invalid card number
            </mat-error>
          </mat-form-field>
          <i class="card ccs ccs-{{type?.card?.type}}" style="float:right;font-size: 30px;width: 28px;margin-bottom: 2%;"></i>
        </mat-grid-tile>
</form>

    control.setErrors({'firstError': null});
    control.updateValueAndValidity();

  }
}

使用Angular材质9的AbstractControl实现存在一个问题。

如果任何人都可以给我快速解决方案或stackbiz链接，这对我将非常有帮助。在哪里可以获得如何设置自定义验证程序错误消息并通过动态方式将其删除。似乎AbstractControl在这里不太合适。 -
