Macros 使用dbt_utils.union_关系错误，但不知道如何/为什么？

所以我是一个新的DBT用户，超级酷的东西，但我遇到了一个关于union_relations宏的问题。我正在将关系馈送到此函数，但编译/运行查询没有从关系中找到任何列

以下是我正在运行的代码：

{{dbt_utils.union_relations(relations=[ref('transform_hist_ca_map_stu_obj_assessment'), ref('transform_hist_sc_map_stu_obj_assessment')])}}


)
select *
from conformed_obj_assessment
where student_assessment_identifier is not null
and assessment_identifier is not null
and identification_code is not null
and student_unique_id is not null
and performance_level is not null

这就是我收到的错误： 第1706行或第1706行附近的语法错误：来自u_dbt__CTE__转换u hist_ca_map_stu obj_a…^在目标/运行/拉力赛/符合/符合学生目标/评估时编译SQL.SQL

基本上，第一列是DBT生成的列，之后的关系中应该有列，但由于某些原因，这些列没有被拉入。我想知道这是否是因为我想从中得到的关系目前只是昙花一现，所以没有具体化，所以我想知道这是否导致了一个问题。这里是编译后的SQL，CTE返回数据，但由于某些原因，它没有被拉入最后一个CTE

任何想法都将不胜感激，谢谢

union_relations宏依赖于了解存储在信息架构中的关系表/视图中的列。由于此模型是短暂的，因此信息模式中没有任何记录，这就是为什么会有这样的SQL：

选择 将“dbt、CTE、转换、历史、地图、目标评估”转换为 瓦尔查尔 作为(dbt)源(source)关系,， 从dbt、CTE、变换、历史、地图、目标评估 我注意到您使用的是一个稍旧的dbt utils版本——虽然我们还没有解决这个问题，但我们已经在v0.5.0中发布了

更新版本的dbt utils将有助于您了解以下信息：

Compilation Error in model test_ephemeral (models/test_ephemeral.sql)

  The `union_relations` macro cannot be used with ephemeral models, as it relies on the information schema.

  `__dbt__CTE__my_ephemeral` is an ephemeral model. Consider making is a view or table instead.` is an ephemeral model. Consider making is a view or table instead.

因此，正如新的错误消息所表明的，唯一的解决方法是将上游模型设置为视图或表。

您可以共享packages.yml文件内容吗？这将有助于告诉我答案！我也这么想，但很高兴得到确认，我没有错误地思考这个问题。谢谢你的帮助！
