Kotlin Corda持久性：未知实体：PersistentFungibleToken 一般说明

你好
我正在试用corda 4.3版token SDK 1.1版，并想尝试各种发行/兑换自定义可替换代币的场景

我编写了一个简单的流程，描述了一方对自己的令牌发行：
虽然非常基本的流似乎工作正常，但在子流（IssueTokensFlow）的中断中，试图将PersistentFungibleToken保存到数据库中（下面是堆栈跟踪）。 我尝试实现自己的模式，但没有成功，因为函数supportedScema（）只需要列表。
我还尝试在不使用定制的FungilbeToken的情况下发行一些代币，但也没有成功。
如何解决这个问题
