I'm having trouble trying to change the BorderPanel Center of my project in javaFX. In the code I call a function that is in the Side-Menu controller to change the Main, but whenever I do this the following error occurs: "Exception in thread" JavaFX Application Thread "java.lang.RuntimeException: java.lang.reflect.InvocationTargetException "
