Identity Server 4 loggs（无效的对象名称'DeviceCodes'）异常

Question

我们正在使用Identity Server 4进行身份验证。将我们的解决方案从.Net Core 2.0升级到.Net Core 3.1之后，我们开始注意到当客户端重定向到我们的身份验证URL时会记录一个新的异常，这不会影响该过程，并且对于最终用户而言一切正常。例外是：

An exception occurred while iterating over the results of a query for context type 'IdentityServer4.EntityFramework.DbContexts.PersistedGrantDbContext'.
Microsoft.Data.SqlClient.SqlException (0x80131904): Invalid object name 'DeviceCodes'.

Error Number:208,State:1,Class:16

导致此异常的查询：

Failed executing DbCommand (2ms) [Parameters=[@__p_0='?' (DbType = Int32)], CommandType='Text', CommandTimeout='30']
SELECT [d].[UserCode], [d].[ClientId], [d].[CreationTime], [d].[Data], [d].[DeviceCode], [d].[Expiration], [d].[SubjectId]
FROM [DeviceCodes] AS [d]
WHERE [d].[Expiration] < GETUTCDATE()
ORDER BY [d].[DeviceCode]

我们在上下文中没有此表'DeviceCodes'，请提供任何建议！

您缺少通过在Package Manager Console窗口中添加迁移而获得（现在已经升级）的DeviceCodes表，如下所示：
