产品组合的Prestashop问题

Question

我添加了一些带有产品组合的产品，但是当我在前端中选择一个产品时，出现此错误：

An error occurred while processing your request

在日志中我发现此sql错误

PrestaShopDatabaseException]
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') GROUP BY pac.id_product_attribute ' at line 8


    SELECT
      pac.`id_product_attribute`
    FROM
      `ps_product_attribute_combination` pac
    INNER JOIN `ps_product_attribute` pa ON pa.id_product_attribute = pac.id_product_attribute
    WHERE
      pa.id_product = 73
    AND pac.id_attribute IN ()
    GROUP BY
      pac.id_product_attribute
    HAVING
    COUNT(pa.id_product) = 0 LIMIT 1

我正在使用prestashop 1.7.6.0 谁能帮我吗？ 谢谢
