javafx error how to fix?

Question

JavaFX

The first application was made according to the guide through SceneBuilder. As a result, some incomprehensible error, I scratched my turnips for 2 hours and did not achieve anything. Please help :(

        this.primaryStage.setTitle("AddressApp");

        initRootLayout();

        showPersonOverview();
    }

            rootLayout = (BorderPane) loader.load();

            // Show the scene containing the root layout.
            Scene scene = new Scene(rootLayout);
            primaryStage.setScene(scene);
            primaryStage.show();
