Why does calling owl.data('owlCarousel') return undefined?

Question

Owl Carousel

I'm using version 2. The carousel works fine except for one thing. Required to get the carousel properties object. This method is recommended, but it returns an empty result.

owl = $('.owl-carousel');
  owl.owlCarousel({ 
      loop           : true,
      margin         : 20,
      nav            : true,
      smartSpeed     : 500,
      dots           : false,
      responsive:{
        0:{
          items : 1
        },
        767:{
          items : 2
        },
        1200:{
          items : 3
        },
  });
  let options = owl.data('owlCarousel');

Why does calling owl.data('owlCarousel') return undefined?
