Not able to display author in Pod List using custom template

[suityou01]

Description

Wordpress 6.6.2

Using pods to create custom content type.

I have a custom template like this

<div class="latestposts">
	<div>{@post_thumbnail}</div>
	<div class="postexcerpt">
		<div>{@post_title}</div>
		<div>{@post_excerpt}</div>
		<div class="tags">
			[each post_tag]
				<span class=newstag>{@title}</span>
			[/each]
		</div>
		<div>
			{@post_date}
		</div>
		<div>
			{@post_author, cc_get_the_author_display_name}
		</div>
	</div>
</div>

I have added a function to my functions.php using the theme file editor

function cc_get_the_author_display_name($userID) {
	return get_the_author_meta( 'display_name', $userID );
}

The output on the page is just the ID value of the author. It looks to me like the filter function is not even being called.
