Hello! Can anybody help me?

[mild wing]

I'm creating a JavaFx Application for a project with a friend. He created the .fxml, .css and controllers we needed, buuut... when i try to run the project (we're using gitHub and Visual Studio Code) this error appears:
Exception in Application start method
java.lang.reflect.InvocationTargetException

We're learning 😦 this is our start function in main:
​​​ public void start(Stage stage) throws Exception { FXMLLoader loader = new FXMLLoader(getClass().getResource("/main/resources/fxml/login.fxml")); loader.setController(new LoginController()); Parent root = loader.load(); Scene scene = new Scene(root); String css = this.getClass().getResource("/main/resources/css/login.css").toExternalForm(); scene.getStylesheets().add(css); stage.setScene(scene); stage.show(); }​​​​
❤️ Thanks for taking your time

Please format your code to make it more readable.
For java, it should look like this:
```​​​`​java
public void foo() {

}
​​​`​```

it shouldn't be /main/resources/...

but just /css/login.css
