      <div class="swiper-pagination"></div>
    @endforeach
  </div>

This line gives no output

<div class="swiper-slide carousel-item-a intro-item bg-image" style="background-image: url({{ asset('uploads/apartments/'.head(json_decode($cover->house_image))) }})">

I dont know the problem cause in controller it gives output
