从BizTalk 2016迁移到BizTalk 2020。
我们有一个发送端口WCF-Custom来执行Oracle过程，但在我们使用BizTalk 2020的新安装中，我们收到以下错误：

Microsoft.ServiceModel.Channels.Common.MetadataException: Metadata resolution failed for OperationId: "http://Microsoft.LobServices.OracleDB/2007/03/BTS/Package/PKG_BTS_PROC/PROCEDUREX". ---> System.NullReferenceException: Object reference not set to an instance of an object.

发送端口具有UseAmbientTransaction = True、Use Transaction = True和enableBizTalkCompatibilityMode = True。
BizTalk 2016中的相同发送端口运行良好，但在BizTalk 2020的新版本中，我们得到了此堆栈跟踪的先前错误：

at Oracle.DataAccess.Client.OracleLogicalTransaction..ctor(OracleConnection connection, Byte[] ltxid)
   at Oracle.DataAccess.Client.OracleException.HandleErrorHelper(Int32 errCode, OracleConnection conn, IntPtr opsErrCtx, OpoSqlValCtx* pOpoSqlValCtx, Object src, String procedure, Boolean bCheck, Int32 isRecoverable, OracleLogicalTransaction m_OracleLogicalTransaction)
   at Oracle.DataAccess.Client.OracleException.HandleError(Int32 errCode, OracleConnection conn, IntPtr opsErrCtx, Object src, OracleLogicalTransaction m_oracleLogicalTransaction)

   at Microsoft.Adapters.OracleCommon.OracleCommonConnectionWrapper..ctor(String connectionString, OracleCommonExecutionHelper executionHelper)
   at Microsoft.Adapters.OracleDB.OracleDBConnection.OpenConnection(OracleCommonExecutionHelper executionHelper)

我们在安装过程中是否遗漏了什么？
