jQuery Problem ! Cannot read property ‘top’ of undefined

After update to new version i have this error on checkout and also if i try to go to the shopping cart, or if i try to empty the shopping cart.

Uncaught TypeError: Cannot read property 'top' of undefined
    at HTMLDocument.<anonymous> (rp-frontend.js?ver=2.7.1:97)
    at i (jquery.js?ver=1.12.4-wp:2)

This is the code of Restropress where the error is:

jQuery( function($) {

  // Sticky category menu on mobile
  var initTopPosition= $('.sticky-sidebar').offset().top;
  $(window).scroll(function(){
    if($(window).scrollTop() > initTopPosition)
      $('.sticky-sidebar').addClass('mobile-sticky');
    else
      $('.sticky-sidebar').removeClass('mobile-sticky');
  });

So, i think it would first check if the jQuery object contains any element before it trys to get its offset:

var TopPosition = $('.sticky-sidebar');
if (TopPosition.length) {
    var initTopPosition = TopPosition.offset().top;
}

Do you agree with me ?

Thanks
