When creating balloonContentLayout using templateLayoutFactory :

 ymaps.templateLayoutFactory.createClass(` <div> BALLOON </div> `, { build: () => { BalloonContentLayout.superclass.build.call(this); }, clear: () => { BalloonContentLayout.superclass.clear.call(this); } });

Balun is positioned in the upper left corner with empty content, and when you try to close, Uncaught TypeError: Cannot read property 'destroy' of null falls out Uncaught TypeError: Cannot read property 'destroy' of null

But if you do not pass the second argument, then everything works correctly. Where is the mistake?

    Case in context. The arrow functions during creation retain their context, and in ordinary ones it floats depending on how they are called. Do this:

     build: function(){ BalloonContentLayout.superclass.build.call(this); }
