我正试图根据产品属性（分类法）从WooCommerce获取特定产品。

$args = array(
            \'post_type\' => array(\'product\', \'product_variation\'),
            \'post_status\' => \'publish\',
            \'tax_query\' => array(
                 array(
                       \'taxonomy\'         => \'pa_range-kwh\',
                       \'terms\'            => \'k2\',
                       \'field\'            => \'slug\',
                       \'operator\'         => \'IN\',
                       \'include_children\' => true,
                        ),
            
            ),
    
    
        );

从SQL的角度来看，我可以看到：

SELECT * FROM `wp_terms` WHERE term_id = 891

退货

SELECT * FROM `wp_term_taxonomy` where term_id = 891

退货

SELECT * FROM `wp_term_relationships` where term_taxonomy_id = 891

退货

虽然至少有一个产品添加了分类法，但由于内部查询返回（0=1），我一直收到0个结果，这意味着它找不到任何具有此分类法属性的产品。

我能做些什么来克服这个问题？
