支架-DbContext抛出ArgumentNullException

Question

当我尝试搭建我们的一个数据库时，出现以下异常。

For foreign key FK_ActivityEvent_ActivityCode on table dbo.ActivityEvent, unable to find the column called UniqActivityCode on the foreign key's principal table, dbo.ActivityCode. Skipping foreign key.
For foreign key FK_Line_Line on table dbo.Line, unable to find the column called UniqLine on the foreign key's principal table, dbo.Line. Skipping foreign key.
For foreign key FK_MarketingLine_MarketingLine on table dbo.MarketingLine, unable to find the column called UniqMarketingLine on the foreign key's principal table, dbo.MarketingLine. Skipping foreign key.

我成功地搭建了一个数据库，因此我确定我正确地使用了scaffold命令。另外，我可以使用在Scaffold-DbContext命令中输入的连接字符串访问数据库。

我安装了以下软件包：

install-package microsoft.entityframeworkcore.sqlserver
install-package microsoft.entityframeworkcore.tools

在Windows 10上使用.NET Core Console App 2.1。

不确定是否与此相关，但是当我尝试在ssms中扩展Database Diagrams时收到以下消息。 （我没有在成功搭建好的其他数据库上收到此消息）
