You don't have the font "Minecraftia.ttf". You can either try to find and 
install it or replace it with another that you already have in the 
/home/pi/.fonts directory.

You may even lie about it, e. g. assuming there is a font called 
"NotoSerif-Regular.ttf"

$ cd /home/pi/.fonts
$ ln NotoSerif-Regular.ttf Minecraftia.ttf

should fix the error without making changes to the code.
