Not able to display author in Pod List using custom template

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.
