'How to set custom font in JavaFX?

I'm trying to set the custom font "Cerebri Sans Regular" to my JavaFX application. I'm using Java SE 11 and JavaFX 11.

My tries:

public class SampleController implements Initializable {

    @FXML
    private Label customFont;
    
    @Override
    public void initialize(URL arg0, ResourceBundle arg1) {
        Font font = Font.loadFont("cerebrisans-regular.ttf", 20);
        
        customFont.setFont(font);
    }
    
}

Error

java.lang.NullPointerException: Cannot invoke "javafx.scene.text.Font.getNativeFont()" because "<parameter1>" is null
    at javafx.graphics/javafx.scene.text.Font$1.getNativeFont(Font.java:68)

Another try from css

@font-face {
    src: url("cerebrisans-regular.ttf");
}

.root {
    -fx-background-color: gray;
    -fx-font-family: "Cerebri Sans"; /* this name is from font file */
}

.customFont {
    -fx-text-fill: red;
    -fx-font-size: 16px;
    -fx-font-family: "Cerebri Sans";
}

Error

The problem was in my working environment name, there was a space. Removed, renamed and now it is working with the CSS code shown in the question.
