I can’t seem to get the categories for a custom post in the loop I have as per the code below: Can anyone help me with what I am doing wrong please?

<?php
    $ids = array();
    $pages = get_pages("child_of=".$post->ID);
    if ($pages) {
        foreach ($pages as $page) {
            $ids[] = $page->ID;
        }
    }
    $paged = (get_query_var("paged")) ? get_query_var("paged") : 1;
    $args = array(
        "paged" => $paged,
        "post__in" => $ids,
        "posts_per_page" => 50000,
        "post_type" => "knowledge_capsules",
        "orderby" => "date",
        "order" => "DESC"
    );
    query_posts($args);
    if (have_posts()) : while (have_posts()) : the_post(); 
?>
    <div class="kcIndex_feedItemWrapper" id="postID<?php echo get_the_ID(); ?>">
         
    <!-- Need to add in the lightbox content here and fire it open on click -->    
        <a href="#" data-featherlight="#IssueExpandedContent_<?php echo get_the_ID(); ?>">
        <img src="<?php the_field('knowledgecapsule_teaser_thumbimg'); ?>" title="<?php the_title(); ?>" alt="<?php the_title(); ?>">
        <h4><?php the_title(); ?></h4>
        
              
            <div class="categoriesHere">
            <?php 
        $terms = get_the_terms( get_the_ID(), 'knowledge_capsules' );
        if(!empty($terms)){
        foreach($terms as $term){
            echo $term->name.'<br>';
        }
        }
        ?>
            </div>
            
         
            
        </a>
    
    <!-- Expanded content -->
    <div id="IssueExpandedContent_<?php echo get_the_ID(); ?>">        
        <?php the_field('knowledgecapsule_teaser_embeddcode'); ?>
        <p class="viewFullVideoLink"><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>">View the full video</a></p>
    </div>
        
    </div>
        
    
    

</div>


<?php endwhile; else: ?>
    <!--<h2>Oh No!!</h2>
    <p><?php _e('Sorry, no posts matched your criteria.'); ?></p>-->
<?php endif; ?>
