Question

我正在使用Corda Enterprise 3.1和R3的Obligation示例代码在Linux服务器环境中进行一些测试。当我尝试执行流时，从启动该流的节点的日志中的公证人那里获得了异常。我在下面粘贴了日志条目。所有节点都被识别为有效节点，但是该消息似乎表明未注册公证流程的客户端。我在哪里注册？我要注册什么？

正在执行的代码是：

val flowHandle = service.proxy.startFlowDynamic(
                IssueObligation.Initiator::class.java,
                issueAmount,
                lenderIdentity,
                true
        )

日志显示此堆栈跟踪：

Answer 1

这是由于未配置公证人。结果，它没有为NotaryFlow$Client安装响应程序流。

您收到的跟踪错误net.corda.core.transactions.FilteredTransaction cannot be cast to net.corda.core.transactions.SignedTransaction.表示，请求公证的节点将公证人错误地标识为无效的，而不是有效的。结果，它发送了错误的交易类型。

NotaryFlow $ Client未注册Corda义务代码中的错误
