Hello,
unfortunately, Facebook request a description for each product as mandatory.
So the only workaround I can suggest you is adding a custom code that adds a default description to all products.
To do that, copy and paste the code below in the functions.php of your current theme or in a new plugin. Here the code:
add_filter('aepc_feed_item', function($params, \PixelCaffeine\ProductCatalog\FeedMapper $item){
if (empty($params['g:description'])) {
$params['g:description'] = 'A default empty message'; // <-- CHANGE HERE WITH SOMETHING OTHER
}
return $params;
}, 10, 2);
I hope that can help you.
Let me know.
