getVectorFont() undefined on Venu 2 SIm - what can I do?

Hello,

I have the following code in the onUpdate function of my watchface (should draw text that is rounded like an arc):

var sz = 20;
var nf=Toybox.Graphics.getVectorFont({:face=>"RobotoItalic", :size=>sz});
dc.drawAngledText(
      200,
      200,
      Graphics.getVectorFont({ :face => "Roboto", :size => 20 }),
      getTime(dc),
      Graphics.TEXT_JUSTIFY_CENTER,
      45
);

But when I run it on the sim, it crashes with this error:

Error: Symbol Not Found Error
Details: Could not find symbol 'getVectorFont'
Stack: 
  - onUpdate() at C:\Users\aaron\GarminDev\SilverWatchFace_copy\source\SilverWatchFaceView.mc:33 0x1000024e 

What could I do to make it work?

Thanks in advance
