Erro para validaçao do form com ReactiveFormsModule

Estou tentando validar meu form, mas estou tomando esse erro no console

ERROR Error: No value accessor for form control with name: 'addName'

esse é meu template

<form
  class="add-user-box-el"
  (submit)="handleAddUser($event)"
  [formGroup]="addForm"
>
  <input formControlName="addName" />
  <input formControlName="addUsername" />
  <input formControlName="addEmail" />
  <div>
    <app-button theme="primary" type="submit">
      Adicionar
    </app-button>
    <app-button theme="secondary" [onClick]="toggleModal()">
      Cancelar
    </app-button>
  </div>
</form>

E aqui meu componente

export class AddUserComponent implements OnInit {
  addForm: FormGroup;

  constructor( private formBuilder: FormBuilder) {}

  ngOnInit(): void {
    this.addForm = this.formBuilder.group({
      addName: ['', Validators.required],
      addUsername: ['', Validators.required],
      addEmail: ['', Validators.required]
    });
  }
}
