I have a problem, I get the error "core.js:4196 ERROR TypeError: Cannot read properties of undefined (reading 'phones')"

The thing is that it tells me that the array of objects that I am going through is empty, when checking a little and doing debugging, I realize that it is not. That actually does not come indefinitely, the data is something big, yes, among 2800 data it brings you almost 5 or 6 phones (since those are what are registered)

Anyway, what I really want to do is get the phone numbers of "x" users from an object and do an autocomplete filtering the data.

I leave you the code, maybe you see something that I don't:

.TS

  contactos: AddContacto[] = [];
  filteredContacts: Observable<AddContacto[]>;
  phoneControl: FormControl = new FormControl();

 this.filteredContactos = this.phoneControl.valueChanges.pipe(
      startWith(null),
      map((search: string | null) => (search ? this._filterContactos(search) : this.contactos.slice())),
    );

private _filterContactos(search: string) {
    const filterValue = search.toLowerCase();
    return this.contact.filter(
      (contact) =>
        !!contact.phones.find((email) => contact.includes(search)) ||
        contact.fullName.toLowerCase().includes(filterValue),
    );
  }

.HTML

<div class="containerTitle p-16">

                <mat-form-field fxFlex="100" class="mr-12" appearance="outline" fxFlex="100">
                    <mat-label>Search Client</mat-label>
                    <input type="text" placeholder="Add email..." matInput [formControl]="phoneControl" [matAutocomplete]="auto">
                    <mat-autocomplete #auto="matAutocomplete" >
                        <mat-option *ngFor="contact of filteredContacts | async" [value]="contact.phones[0]">
                            {{contact?.phones[0]}} {{contact?.fullName ? '('+ contacto?.nombre_completo +')' : ''}}
                        </mat-option>
                    </mat-autocomplete>
                </mat-form-field>
                <small-loading class="loadingProgressBar" [loading]="loading"></small-loading>
            </div>

Object

0: {
    "state": true,
    "coments": null,
    "phones": ["22222222"],
    "emails": [
        "email@gmail.com"
    ],
    "fullName": "",
    "_id": "",
    "bitacora": {},
    "__v": 0
}

Thanks!!
