Help retrieving values from ACF custom fields in custom PHP Theme Pattern

Hi all,

I’m struggling to retrieve values from my ACF custom fields in a new custom PHP pattern I’ve created for my theme. I have a custom field with the slug ‘test’, and I’m trying to retrieve it in the pattern’s code using a ‘get_field’ function.

I’ve been adding this pattern to a custom post type (made using CPT UI) called ‘work’, and only a blank paragraph box has been showing.

Any ideas? I don’t have ACF Pro (if that’s required in this instance..)

<?php
/**
 * Title: Credits List
 * Slug: squeake/credits-list
 * Categories: text
 * Description: A credit list for a piece of work.
 */
?>
<!-- wp:group {"align":"wide","layout":{"type":"constrained"}} -->
<div class="wp-block-group alignwide">
    <!-- wp:paragraph {"align":"center","style":{"typography":{"lineHeight":"1"}},"fontSize":"max-23"} -->
    <p>
        <?php 
        $text = get_field('test');
        echo $text;
        ?>
    </p>
    <!-- /wp:paragraph -->
</div>
<!-- /wp:group -->
