null pointer exception on filling java fx table

I'm trying to set items to the

@FXML
    private TableView<Price> pricesTable;

where the following columns defined:

 @FXML
    private TableColumn<Price, Long> priceId;
    @FXML
    private TableColumn<Price, Good> priceGood;
    @FXML
    private TableColumn<Price, MeasurementUnit> priceMeasurement_unit;
    @FXML
    private TableColumn<Price, TypeOfPrice> type_of_price;
    @FXML
    private TableColumn<Price, Long> price;

using such code:

private void updatePrices() throws SQLException{
        pricesPane.setCenter(pricesTable);
        pricesTable.setItems(FXCollections.observableArrayList(pricesService.getPrices()));
        pricesTable.getSortOrder().add(priceId);
    }

where pricesService is the following:

public class PricesServiceImpl implements PricesService {
    private final Dao<Price, Long> pricesDao = DaoFactory.getDao(Price.class);
    private Logger log = LogManager.getLogger(PricesServiceImpl.class);

    @Override
    public List<Price> getPrices() throws SQLException {
        try {
            List<Price> prices = pricesDao.queryForAll();
            return prices;
        } catch (SQLException e) {
            log.log(Level.DEBUG, e.getMessage());
            e.printStackTrace();
        }
        return Collections.emptyList();
    }
    @Override
    public void removePrice(Price price){
        try{
            pricesDao.delete(price);
        }catch (SQLException e){
            log.log(Level.ERROR, e.getMessage());
        }
    }
    @Override
    public void savePrice(Long id, Good good, MeasurementUnit measurementUnit, TypeOfPrice typeOfPrice, Long priceValue){
        Price price = new Price();
        price.setId(id);
        price.setGood(good);
        price.setMeasurementUnit(measurementUnit);
        price.setPrice(priceValue);
        price.setTypeOfPrice(typeOfPrice);
        try {
            pricesDao.create(price);
        }catch (SQLException e){
            log.log(Level.ERROR, e.getMessage());
        }

    }

}

On compilation I'm constantly getting an error caused by: java.lang.NullPointerException on string with setItems. I have several tables that gives the same error on their filling. So I cant figure out what is wrong. Maybe the reason of the error is that I'm trying to fill some columns with objects?

UPD: here is prices service init:

private PricesService pricesService = ServiceProvider.getService(PricesService.class);

serviceProvider is the following:

public class ServiceProvider {
    private ServiceProvider() {}
    private static Map<Class<? extends Service>, Service> serviceMap = new HashMap<>();
    static {
        serviceMap.put(AgentsService.class, new AgentsServiceImpl());
        serviceMap.put(GoodsService.class, new GoodsServiceImpl());
    }
    @SuppressWarnings("unchecked")
    public static <Type> Type getService(Class<Type> type) {
        return (Type) serviceMap.get(type);
    }

}
