Error with function wcgwp_get_products

Hi,

I have daily errors in log file from your plugin:
Gift Wrapper didn’t come up with any wrap products in wcgwp_get_products() get_posts. Review the args and maybe use the ‘wcgwp_get_posts_args’ filter hook to help get results.

I found out that this is in “includes/functions.php” on line 66 where whole function wcgwp_get_products is set. But i don’t understand what this happens ? I only have this part on cart page and it works ok, if i got to cart and try to select everything works fine and i don’t get error log.
So i am not sure where the error happens.

Thank you in advance.
