I face the same error as well & able to fix.

Exception in thread "JavaFX Application Thread" java.lang.IllegalArgumentException: argument type mismatch

Here is how your code suppose to look like

@FXML
public void loadDC1(ActionEvent event){
    ToggleButton btnSelected = (ToggleButton) event.getSource();

    String name=btnSelected.getId().toString();

    if(name.equalsIgnoreCase("toggleDC1")){
          //do something
    }
}

in JavaFX, you need to define all fx:id, #action in your fxml files into controller class like;

@FXML private ToggleButton toggleDC1; // as a class field

@FXML public void loadDC1(ActionEvent event){} // method
