我用insert into select 外部catalog表 插入数据，报错:
失败: errCode = 2, detailMessage = (10.10.0.64)[RUNTIME_ERROR]JdbcExecutorException: jdbc get block address: | CAUSED BY: RuntimeException: the result of 2185 row is null, but the return type is not nullable, please check the always_nullable property in create function statement, it's should be true
按意思就算有字段是null的，但我定义字段类型是not null的，但按以下DDL:

首先除了key ID 之外，所有字段都定义是可以null的，key肯定不为null的，而且我在select中其他的字段也用COALESCE 做了处理，也不可能是空的，
我目前知道的是 adjusted_price_end_at 这字段造成的，只要where 上加上 adjusted_price_end_at is not null ，就都能写入，但观察不出这个字段和其他字段有什么区别，就是直接加默认值也不行，请问大概是什么问题？是bug吗？还是需要有些特殊处理技巧？
