Uncaught Error: Call to a member function get_id()

Hi, a few times a week I get the following PHP error. Is it woocommerce or Fast Woo Order Look UP ?

Fatal error: Uncaught Error: Call to a member function get_id() on bool in /var/www/html/mysite.net/wp-content/plugins/woocommerce/src/Internal/DataStores/CustomMetaDataStore.php:60
