What is the best way to implement search by matAutocomplete and autocomplete fields?

Question

JavaScript

There is an array of objects unloaded from PostgreSQL: (modelModel consists, let's say of id (number) and name(string) ) There is such a field with autocompletion:
массив$: Observable<Array<модельModel>>;

<mat-form-field>
              <input matInput
                     placeholder="Номер модели"
                     formControlName="id"
                     [matAutocomplete]="auto">
              <mat-autocomplete #auto="matAutocomplete">
                <mat-option *ngFor="let массив of массив$ | async"
                            [value]="массив.id">
                  {{ массив.id }}
                </mat-option>
              </mat-autocomplete>
            </mat-form-field>

and there is just

<mat-input-container>
                <input matInput
                     formControlName="name"
                     placeholder="Имя модели"
                     readonly>
            </mat-input-container>

If I follow the example from https://material.angular.io , the search does not work (more precisely, it swears in the ts file that the ModelModel does not have any name).
And you need to do the following:
search by matAutocomplete
and automatically load the associated value in input formControlName="name".
I would be grateful for even the slightest hints and guidance. Or alternatives =)
All names are fictitious and coincidences are random!
PS For errors I apologize, more the end of the working day.
