How to show the correct date in format of datepicker in Angular material

I have a Angular 8 application. And I am using the Datepicker of material.

But if I fill in a date an call the get api call: 

  searchFor(filterRegistration: FilterByRegistrationDTO) {
    // tslint:disable-next-line: max-line-length
    console.log(
      this.participantService.filterParticipantsByRegistration(1, "Invited", this.startDate.toString()).subscribe(result => {       
        console.log(this.startDate.toString());
        console.log(result);
      })
    );

And the template looks like this:

    <div>
      <mat-form-field  class="search-field-input">
        <input matInput [matDatepicker]="picker1" placeholder="start datum" [(ngModel)]="startDate"  />
        <mat-datepicker-toggle matSuffix [for]="picker1"></mat-datepicker-toggle>
        <mat-datepicker #picker1></mat-datepicker>
      </mat-form-field>
    </div>

So on the server side the date will be show as: jjjj-MM-dd.

But on the client side the date has to been shown as: dd-MM-jjjj.

But so if I call the api call:

console.log(
      this.participantService.filterParticipantsByRegistration(1, "Invited", this.startDate.toString()).subscribe(result => {
        console.log(this.startDate.toString());
        console.log(result);
      })
    );

Then I will get this error:

core.js:12584 ERROR 
HttpErrorResponse {headers: HttpHeaders, status: 400, statusText: "Bad Request", url: "https://dev-engine.mijnhep.nl/api/medical/organisa…GMT%2B0200%20(Central%20European%20Summer%20Time)", ok: false, …}
error:

__proto__: Object

name: "HttpErrorResponse"
ok: false

__proto__: HttpResponseBase

So my question is. how to fill in the correct date format on the client side. So that it will not thrown an error?

Thank you

You can use the iso date format using JSON.stringify(yourDate)

then on server side just use this value.

Otherwise, on client side, you can use moment(yourDate).format('L');

https://momentjs.com/

In your code, it would be:

this.participantService.filterParticipantsByRegistration(1, "Invited", JSON.stringify(this.startDate))

or 

this.participantService.filterParticipantsByRegistration(1, "Invited", moment(yourDate).format('L'))
