It seems like get_the_ID() can also be of type false; however, parameter $post_id of get_post_meta() does only seem to accept integer, maybe add an additional type check?

It seems like $product_ids can also be of type string. However, the property $product_ids is declared as type array. Maybe add an additional type check?

It seems like false of type false is incompatible with the declared type array of property $product_ids.
