Encountering an error message related to Bootstrap carousel: "Unable to read property 'offsetWidth' of undefined"

Encountering a frustrating error message: "Cannot read property 'offsetWidth' of undefined" when using Bootstrap carousel.

Let me share my code with you:

 <div id="myCarousel" class="carousel slide" >
    <ul class="carousel-indicators">
        <?php foreach ($repairPics as $ind => $pics) {  ?>
            <li data-target="#myCarousel" data-slide-to="<?php echo $ind;?>" <?php echo (($ind == 0) ? 'class="active"' : '');?>"></li>
        <?php } ?>
    </ul>
    <div class="carousel-inner" role="listbox" style="margin-left: 10%;height: 100%;">
        <?php foreach ($repairPics as $ind => $pics) {  ?>
            <div class="carousel-item <?php echo (($ind == 0) ? 'active' : '');?>">
            <img style="height: 100%;" class="d-inline-block w-100" src="https://earthsky.org/upl/2017/06/Interplanetary-Transport-System-SpaceX-Elon-Musk-300x158.jpg" alt="Starship">
            </div>
        <?php } ?>
     </div>
    <a class="carousel-nav-controls carousel-control-prev" href="#myCarousel" data-slide="prev">
        <span class="fa fa-chevron-left"></span><span class="sr-only">Previous</span>
    </a>
    <a class="carousel-nav-controls carousel-control-next" href="#myCarousel" data-slide="next" style="right: 0%;">
        <span class="fa fa-chevron-right"></span><span class="sr-only">Next</span>
    </a>
  </div>
</div>

Now, let's have a look at my JavaScript code:

  $("#myCarousel").carousel();

  $(".carousel-item").click(function(){
        $("#myCarousel").carousel(0);
  });

  $("a.carousel-nav-controls.carousel-control-prev").click(function(){
        $("#myCarousel").carousel("prev");
  });

  $("a.carousel-nav-controls.carousel-control-next").click(function(){
                $("#myCarousel").carousel("next");
   });

Trying to figure out the root of the error. Any insights?

Warm Regards, Kevin

Answer №1

Solution Found:

After investigation, it was discovered that the issue did not stem from the Javascript code or any active settings. The problem was actually related to the carousel-item class. By simply changing it to 'item', the issue was resolved and the functionality is now working properly. It appears that upgrading Bootstrap may also be necessary in the near future.
