Meta Box

Hi there!,
I created an slider for images using a custom block and custom assets for that block and everything is working fine on the front-end but isn't working completely because when I'm editing the page that contain that block the javascript files are not executing because the carousel isn't moving I think I called them correctly and are loading without problems but something isn't working and I can't figure it out what is the problem.
Do you know if I need to put something else to make this slider works correctly?
I would like to know if anyone can help me with this please.
Thank you

CUSTOM ASSETS CALLBACK

function slider_js(){
    if(is_admin()){
        //ADMIN NOT EXECUTING THE JAVASCRIPT INIT BUT ARE LOADING WITHOUT PROBLEMS
        $template_url = get_template_directory_uri();
        wp_enqueue_style('swiper-slider-css', $template_url .   '/assets/css/swiper-bundle.min.css', [], null);
        wp_enqueue_script('swiper-slider-js', $template_url .   '/assets/js/swiper-bundle.min.js', [], null, true);
        wp_enqueue_script('swiper-slider-init', $template_url. '/blocks/slider/js/slider.js', ['swiper-slider-js'],null, true);
    }else{
        //FRONT-END WORKS PRETTY WELL
        $template_url = get_template_directory_uri();
        wp_enqueue_script('swiper-slider-init', $template_url. '/blocks/slider/js/slider.js', [],null, true);
    }
}

SWIPER SLIDER INIT

const slider = new Swiper('.slider-swiper .swiper-container', {
    speed: 700,
    loop:true,
    lazy: {
      loadPrevNext: true,
      loadPrevNextAmount: 2,
    },
    parallax: true,
    autoplay: {
          delay: 4600,
          disableOnInteraction: false,
    },
    pagination: {
      el: '.slider-swiper .swiper-pagination',
      clickable: true,
    },
    navigation: {
      nextEl: '.slider-swiper .swiper-button-next',
      prevEl: '.slider-swiper .swiper-button-prev',
    },
});    

Hi Long, Thank you for your help.
I was reading the documentation and I tried to use some custom assets on the block render area (using the AIO plugin) I can't get it work correctly.

When I did a preview of the code I saw that the functions() is displaying as a string and not outside of that string to call more assets.

Do you have some ideas that can I use to solve that?

Thank you

Thank you! I updated my PHP version and now is solved 🙂

PROBLEM SOLVED!,
Never mind,
I updated my WordPress to the latest version and now is working fine,
Thanks
