Show text in 3d pyqtgraph, using GLTextItem class of GLGraphicsItem python

The below code is for creating a GLTextItem from GLGraphicsItem but when the object is called it gives the error

"Error while drawing item <gl_classes.GLTextItem object at 0x000001D903BB34C0>."

        self.text = text
        self.X = X
        self.Y = Y
