N功能最初是按照要求工作的，但是在新的部署之后，或者在服务器上几天没有活动的情况下，我开始得到异常或者流不能像预期的那样工作。我当前收到以下异常- com.sc.corda.server.exception.CordaFlowException: com.sc.corda.node.exception.SCFlowException:无法公证安全事务！附件中有完整的exception.Could，有谁能帮我找到解决方案

Answer 1

com.sc.corda.server不是Corda的错误前缀之一。而且Unable to Notarize Security Transactions!不是Corda的错误消息之一。

它是由您实现的服务器生成的。我的猜测是您的服务器试图启动一个流，但是流失败了，并显示了您定制的错误消息，指出它无法对安全事务进行公证。
