I have code that returns data from back-end

Here is it

 @Injectable()
export class DictionariesDatasourceFacadeService {
  public invoiceTemplate: IDataSource<IComboboxItem>;
  public replacedLegalEntity: IDataSource<IComboboxItem>;
  public salesOrderTemplate: IDataSource<IComboboxItem>;
  public deliveryNoteTemplate: IDataSource<IComboboxItem>;
  public createInvoiceAction: IDataSource<IComboboxItem>;
  public clientPortal: IDataSource<IComboboxItem>;

  private readonly dataSourceFactory = inject(DataSourceFactory);
  private readonly invoiceTemplateService = inject(InvoiceTemplateService);
  private readonly replacedLegalEntityService = inject(LegalEntityService);
  private readonly salesOrderTemplateService = inject(SalesOrderTemplateService);
  private readonly createInvoiceActionService = inject(CreateInvoiceActionService);
  private readonly deliveryNoteTemplateService = inject(DeliveryNoteTemplateService);
  private readonly clientPortalService = inject(ClientPortalService);

  public constructor() {
    this.init();
  }

  private init(): void {
    this.invoiceTemplate = this.createGenericDataSource(this.invoiceTemplateService.getSimpleInvoiceTemplates());
    this.replacedLegalEntity = this.createGenericDataSource(this.replacedLegalEntityService.getSimpleLegalEntities());
    this.salesOrderTemplate = this.createGenericDataSource(
      this.salesOrderTemplateService.getSimpleSalesOrderTemplates()
    );
    this.deliveryNoteTemplate = this.createGenericDataSource(
      this.deliveryNoteTemplateService.getSimpleDeliveryNoteTemplates()
    );
    this.createInvoiceAction = this.createGenericDataSource(
      this.createInvoiceActionService.getAlgorithms()
    );
    this.clientPortal = this.createGenericDataSource(this.clientPortalService.getActiveClientPortals());
  }

  private createGenericDataSource<T extends IComboboxItem>(method: Observable<T[]>): IDataSource<IComboboxItem> {
    return this.dataSourceFactory.createLocalDataSource(
      () => method.pipe(map(x => x.sort(sortByName))),
      filterByNameFn
    );
  }
}

On row this.createInvoiceActionService.getAlgorithms() I got those errors.

But I don’t see any any types

How I can solve this error?
