using the_field in filters

I’m trying to customise the carousel with the wpc_item_description filter in functions.php, but it seems like functions like get_field won’t work there – the page stops rendering at the point where I call it. What am I missing?

function my_wpc_item_description( $description, $params ) {

	$post_content = get_the_content();
	$topic = get_field('topic-name');

	$description = '<div class="wp-posts-carousel-desc">
<div class="main-content"> ' . $topic . '</div>
</div>';

	return $description;
}
add_filter('wpc_item_description', 'my_wpc_item_description', 1, 2);
