Getting file field URL from term child

I’m trying to provide a direct download link on a page that displays posts from categories in a custom taxonomy. I have everything working except the link, which currently just links to the main page as my $url variable is not working. Where have I gone wrong?:

$term = get_queried_object();
					$term_id = $term->term_id;
					$taxonomy_name = $term->taxonomy;

					$termchildren = get_term_children( $term_id, $taxonomy_name );

					echo '<ul>';
					    foreach ( $termchildren as $child ) {
					        $childTerm = get_term_by('id', $child, $term->taxonomy );
					        echo '<li><a href="' . get_term_link( $childTerm, $term->taxonomy ) . '">' . $childTerm->name . '</a>';

					        // posts with this term         
					        $childTermPosts = get_posts(array(
					          'post_type' => 'cpt_downloads', // WTV your post_type is for Downloads tax
					          'numberposts' => -1,
					          'tax_query' => array(
					            array(
					              'taxonomy' => $taxonomy_name,
					              'field' => 'id',
					              'terms' => $child,
					              'include_children' => true
					              )
					            )
					        ));

					        // then loops the posts
					        if (count($childTermPosts) > 0) {
					            echo "<ul>";

					            foreach ($childTermPosts as $childTermPost) { 

									$file = get_field('download', $childTermPost->ID);

									if( $file ) {

										$url = wp_get_attachment_url( $file );

										echo "<li><a href='".$url."'>{$childTermPost->post_title}</a></li>";
									}
									
								}
								
					            echo "</ul>";
					        }
					
					        echo "</li>";
					
					    } //end foreach

					    echo '</ul>';
