Всем привет. У меня возникает одна ошибка(выше скрин) при инжекте

export abstract class DataSourceBaseEntity<T> extends DataSource<T>{ public dataSourceSubjects = new BehaviorSubject<T[]>([]); public allSourceSubjects: Array<T>; public apiClient: any; constructor( public loadingSubject?:Subject<boolean>){ super(); console.log("constructor DataSourceBaseEntity") this.loadingSubject = new BehaviorSubject<boolean>(true); } abstract loadSubjects(): Observable<T[]>; } @Injectable() export class WarehouseTableDataSource extends DataSourceBaseEntity<TaxpayerStoreSimpleDto> { public loading = this.loadingSubject.asObservable(); loadSubjects(): Observable<TaxpayerStoreSimpleDto[]>{ return this.apiClient.getUserTaxpayerStores().pipe( catchError(() => of([])), finalize(() => this.loadingSubject.next(false)), ) } } @Component({ selector: 'app-warehouse', templateUrl: './warehouse.component.html', styleUrls: ['./warehouse.component.scss'], providers: [WarehouseTableDataSource], }) export class WarehouseComponent implements OnInit, OnDestroy { menuItems: any[]; filterForm: FormGroup; displayedColumns: string[] = ["name",'externalId',"warehouseTypeCode", "status","address","isDefault","isPostingGoods","isInherited","isJointStore","isCooperativeStore","isRawMaterials", 'responsiblePersonIin']; reorginized = REORGANIZED; warehouseUDSs = WAREHOUSESUDSS; statuses = STATUSES; private unsubscription$: Subject<void> = new Subject<void>(); public get TaxpayerStoreStatus(): typeof TaxpayerStoreStatus { return TaxpayerStoreStatus; } public get TaxpayerStoreType(): typeof StoreType { return StoreType; } constructor( taxPayerApi: TaxpayerStoreClient, private formBuilder: FormBuilder, private commonValuesService: CommonUpdateValuesService, private titleService: Title, public dataSource: WarehouseTableDataSource) { this.dataSource.apiClient = taxPayerApi; this.titleService.setTitle('Склады'); } ngOnInit() { this.filterForm = this.formBuilder.group({ warehouseName: [], reorganizedWarehousePerson: [], warehouseUDS:[], statusWarehouse: [] }); this.dataSource.loadSubjects() .pipe(takeUntil(this.unsubscription$)) .subscribe((data) => { this.dataSource.dataSourceSubjects.next(data); }); } ngOnDestroy(): void { console.log("warehoudse component destroyed") this.unsubscription$.next(); this.unsubscription$.complete() } }

503, я долго ждал)

я решил проблему убрав из конструктор абстрактного класса параметр public loadingSubject?:Subject<boolean> и выносил его вне конструктора.
