Переключение между окнами по кнопке JAVAFX

Question

возникла вот такая проблема: Хочу сделать переключение между окнами по кнопке в javaFX, но почему - то выходит данная ошибка:

    at
com.system.system/com.system.system.HelloController.lambda$initialize$1(HelloController.java:50)

Код перемещения по кнопке:

loginSingUpButton.setOnAction(actionEvent -> {
    loginSingUpButton.getScene().getWindow().hide();

    FXMLLoader loader = new FXMLLoader();
    loader.setLocation(getClass().getResource("/com.system.system/signUp.fxml"));

    try {
        loader.load();
    } catch (IOException e) {
        e.printStackTrace();
    }

    Parent root = loader.getRoot();
    Stage stage = new Stage();
    stage.setScene(new Scene(root));
    stage.showAndWait();
});

Весь код HelloController:

p

ackage com.system.system;

import java.io.IOException;
import java.net.URL;
import java.util.ResourceBundle;

import javafx.event.Event;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.PasswordField;
import javafx.scene.control.TextField;
import javafx.stage.Stage;

public class HelloController {

    @FXML
    private ResourceBundle resources;

    @FXML
    private URL location;

    @FXML
    private Button authSigninButton;

    @FXML
    private Button loginSingUpButton;

    @FXML
    private TextField login_field;

    @FXML
    private PasswordField password_field;

    @FXML
    void initialize() {
        authSigninButton.setOnAction(actionEvent -> {
            System.out.println("Нажатие на кнопку \"Войти\"");
        });

        loginSingUpButton.setOnAction(actionEvent -> {
            loginSingUpButton.getScene().getWindow().hide();

            FXMLLoader loader = new FXMLLoader();
            loader.setLocation(getClass().getResource("/com.system.system/signUp.fxml"));

            try {
                loader.load();
            } catch (IOException e) {
                e.printStackTrace();
            }

            Parent root = loader.getRoot();
            Stage stage = new Stage();
            stage.setScene(new Scene(root));
            stage.showAndWait();
        });

    }

}
