MatDatepickerInputEvent requires 1 type argument

Question

I have a date picker on the picker I add the dateChange event for catch the event in ts

html date picker field

<mat-form-field class="date-picker-field picker" floatLabel="always" appearance="fill">
  <mat-label>Період від</mat-label>
  <input [max]="maxDay" (dateChange)="fromDateChangeEvent($event)" matInput [matDatepicker]="dp3">
  <mat-datepicker-toggle matSuffix [for]="dp3">
    <mat-icon matDatepickerToggleIcon>
      <img src="../../../../../../../assets/img/system/ic-system-calendar.svg" alt="">
    </mat-icon>
  </mat-datepicker-toggle>
  <mat-datepicker #dp3 disabled="false"></mat-datepicker>
</mat-form-field>

typescript file

Here I'm catching the event

  fromDateChangeEvent(beforeDate: MatDatepickerInputEvent): void {
    this.minDay = new Date(beforeDate.target.value);
  }

but on the time of compiling time I'm getting this error in the console

Generic type 'MatDatepickerInputEvent<D>' requires 1 type argument(s). 

I tried to add string or number as a type,like this

  fromDateChangeEvent(beforeDate: MatDatepickerInputEvent<string | number>): void {
    this.minDay = new Date(beforeDate.target.value);
  }

But I got the same error, I'd not like to add any type
