当我在一个.net-core 3.1应用程序中从MySQL Client 8.0.20升级到8.0.21时，我在试图调用AWS Aurora中的存储过程时遇到了这个奇怪的错误。

MySql.Data.MySqlClient.MySqlException (0x80004005): same name are not supported.
   at MySql.Data.MySqlClient.ProcedureCache.GetProcData(MySqlConnection connection, String spName)
   at MySql.Data.MySqlClient.ProcedureCache.AddNew(MySqlConnection connection, String spName)
   at MySql.Data.MySqlClient.ProcedureCache.GetProcedure(MySqlConnection conn, String spName, String cacheKey)
   at MySql.Data.MySqlClient.StoredProcedure.CheckParameters(String spName)
   at MySql.Data.MySqlClient.StoredProcedure.Resolve(Boolean preparing)
   at MySql.Data.MySqlClient.MySqlCommand.ExecuteReader(CommandBehavior behavior)

在8.0.20（以及之前的几个版本）中，它工作得没有任何抱怨。我在Intertubes上找不到任何关于这个错误的信息。
过程（非常简单的搜索过程）：

CREATE DEFINER=`cdapoe`@`%` PROCEDURE `find_oeauthorizationassigned`(
IN p_username VARCHAR(120),
IN p_active_utc DATETIME
)
    READS SQL DATA
select * from oeauthorization.oeauthorizationassigned
where username=p_username and (p_active_utc < expiration_utc or expiration_utc is null)
