Uncaught TypeError: Cannot read properties of undefined (reading 'children')

[elmonty]

I have set up Swiper according to the documentation but when I try to run it, I get this error:

swiper-bundle.min.js:13 Uncaught TypeError: Cannot read properties of undefined (reading 'children')
    at h (swiper-bundle.min.js:13:4009)
    at Q.getSlideIndex (swiper-bundle.min.js:13:52129)
    at Q.loopFix (swiper-bundle.min.js:13:29698)
    at Q.slideNext (swiper-bundle.min.js:13:26037)
    at home.js:28:10

Here's my HTML:

<div class="swiper" id="banner-slider">
	<div class="swiper-wrapper">
		<div class="swiper-slide"><img src="images/home/banner/banner_1.jpg"></div>
		<div class="swiper-slide"><img src="images/home/banner/banner_2.jpg"></div>
		<div class="swiper-slide"><img src="images/home/banner/banner_3.jpg"></div>
		<div class="swiper-slide"><img src="images/home/banner/banner_4.jpg"></div>
	</div>
	
	<div class="swiper-pagination"></div>
	<div class="swiper-button-prev"></div>
	<div class="swiper-button-next"></div>
</div>

Hi,

Got this to work as expected. Please provide full code example ?
