Nprinting prints blank object - Extensions made in Nebula.js

[MATC]

Hello,

Is there a function that makes object compliant to Nprinting rendering? or how to implement this into our extension paint : function() { return qlik.Promise.resolve(); }

I mean to ensure Nprinting that the object has rendered before it is printed (now it is printing blank object - whenever there's lower amount of data it is printing okay)
