openlayers error on draw/modify (in vuejs)

The code I am using is in my previous question (resolved)

The interaction works perfectly and my goal is to get an array of coordinates, also works perfectly. Although everything works, I am getting an error in console every time I move the mouse in the display area. It doesn't affect functioning, but obviously I need to solve it... any ideas?

Draw.js?ac29:579 Uncaught TypeError: Cannot read property 'getGeometry' of null

I'm trying something quite random, but you maybe want to add some condition in you current code:

var modify = new Modify({source: source});
modify.on('modifyend',function(e){
   if(e.features && e.features.getArray().length) { //add this line
      console.log("feature id is",e.features.getArray()[0].getGeometry().getCoordinates()[0]);
   }
});
