我正在使用一个从视图创建的数据实体。场景是PowerBI将通过来自d365实例的“/data”url使用该实体。当请求实体并生成json时,不会发生任何事情。当我从浏览器中打开WebDeveloperTools并请求该实体的url时,出现以下错误:

    }
  }
}

数据源是一个名为“tsTimesheetsmmaryline”的视图。我复制了另一个实体,删除了其中的所有内容,删除了作为datasource的视图,然后将所有字段从datasource拖放到实体的字段中

看起来真实的数组可以在视图中使用,但不能在实体中使用。导致此异常的字段是“小时”,它存储7个实际值(一周中的每一天一个)。
