Undefined array key ‘condition’

Hello,
I use ACF with Fluentsnippets, I create my PHP code using Content PHP + HTML in my articles.
The PHP code used:

<?php
$reference = get_field('reference');
	if( $reference ): ?>
<p><b>Ref. :</b> <?php the_field('reference');?></p>
<?php endif; ?>

I get the following error when I go to my article page, to insert the code I use Shortcode:

Warning: Undefined array key ‘condition’ in /var/www/clients/client2/web41/web/wp-content/plugins/easy-code-manager/app/Hooks/Handlers/CodeHandler.php on line 96

WP 6.4.2 Theme: Ollie and tested with Twenty Twenty-Four

THANK YOU
