The conflict occurred in database "xxx", table "dbo.xxx", column ‘xxx’. The underlying SQL Server table has a Race column defined as nullable nvarchar(50) with a foreign key constraint to a related Races lookup table.

Sql Exception: The INSERT statement conflicted with the FOREIGN KEY constraint "FK_xxx".
