Question

Hello Corda团队，

我已经创建了factorial oracle服务并在Corda M13中创建了两个派对流程。

从控制台执行流程时出现以下错误。

co.paralleluniverse.fibers.SuspendExecution：糟糕。忘了检测方法使用-Dco.paralleluniverse.fibers.verifyInstrumentation = true运行程序抓住罪魁祸首！

From logs, i found following warning message:

Answer 1

您似乎错过了某个流量的@Suspendable注释，或者您从流程中调用的其中一种方法。

最好是自由地添加注释以查看它是否删除了错误，然后逐渐减少以查看哪个是有问题的方法。

在CordaM13中执行流程时获取异常 - co.paralleluniverse.fibers.SuspendExecution
