创建物化视图时，distinct 字段的问题

[小马过河]

表是主键模型，starrocks 版本是2.3

报错如图 ，我应该怎么调整啊 请老师指点一下。sql：

CREATE MATERIALIZED VIEW znzc_test.dws_delivery_record AS
SELECT delivery_id,car_series_code,bitmap_union(to_bitmap(vin)) ,SUM(action_status)
FROM znzc_test.dwd_delivery_record GROUP BY delivery_id , car_series_code;

这样试试
CREATE MATERIALIZED VIEW znzc_test.dws_delivery_record AS
SELECT delivery_id,car_series_code,bitmap_count(bitmap_union(to_bitmap(vin)) ),SUM(action_status)
FROM znzc_test.dwd_delivery_record GROUP BY delivery_id , car_series_code;
