javafx error 'exception in Application start method' after trying to use an image

Question

I have the code:

package sample;
import javafx.scene.Group;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
import javafx.scene.paint.Color;
import javafx.scene.image.Image;
//import java.awt.*;
import javafx.stage.Stage;

public class Main extends Application {
    public static void main(String[] args) {
        launch(args);
    }


    @Override
    public void start(Stage primaryStage) throws Exception{
        Group root = new Group();
        Scene scene = new Scene(root,Color.BLACK);

        Image icon = new Image("red dot.png");
        primaryStage.getIcons().add(icon);
        primaryStage.setTitle("Hello stage title");

        primaryStage.setScene(scene);
        primaryStage.show();

    }

}

My project structure is:

This is the error I get:
