Reply To: Post Object at random

As I stated I now have an option to pick a molecule of the day. But I want one at random to load. In ACF we have a motd block with Field Type post object. This seems to create a setup where you can choose an item from the existing ones for the post object or search for one.

How can we load a post at random using an ACF Block from the editor with a Gutenberg Block?

current code:

<?php
// ACF updated to work with new block
$motd = get_field('motd');
var_dump($motd); // NULL
$molecule_month = get_the_terms($motd->ID , 'molecules_of_the_month' ); 
var_dump($molecule_month); // warning trying to read property ID on NULL

?>

<div id="<?php echo esc_attr($id); ?>" class="<?php echo esc_attr($className); ?>">

<?php
// $molecule_month = get_the_terms($motd->ID , 'molecules_of_the_month' );
// $month = array_pop($molecule_month);
// $molecule_link = get_term_link( $month->term_id, 'molecules_of_the_month' );

// Set the post type here, and sort them randomly
// molecule of the month presented as random molecule of the day.
$args = array(
    'post_type' => 'molecule',
    'posts_per_page'=> 1, 
		'post_category' => 'molecule_of_the_month',
    'order_by' => 'rand',
);
// Initiate a custom query
	
$cpt_query = new WP_Query($args);
	
// If the query has any post, start the loop
if($cpt_query->have_posts()){
    while($cpt_query->have_posts()){
        // Output a link and a thumbnail of the post
        $cpt_query->the_post(); ?>
        <div class="random-post">
					<div class="motd-img">
						<a href="<?php echo $molecule_link ?>">
								<?php echo get_the_post_thumbnail( 'full');?>"/>
						</a>
					</div>
					<div class="motd-content">
						<h2 class="is-style-highlight">Molecule of the day</h2>
						<h3 class="motd-name">
							<a href="<?php // echo $molecule_link ?>">
							<?php // echo esc_html( $title ); ?><?php // if($month){ ?> - <?php //echo $month->name; } ?>
							</a>
						</h3>
						<a href="<?php the_permalink();?>"><?php the_title();?></a>
					</div>
        </div>
				<?php
    }
} ?>
