net.corda.core.flows.UnexpectedFlowEndException:试图使用空缓冲区访问已结束的会话SessionId（toLong=8223329095323268472）

我使用Corda 4.0 RC1，并拥有现金发行人存储库的克隆；我有一个Corda ResponderFlow，它应该做一个商业测试；目前它抛出一个异常；流程是以这种方式编程的

class ReceiveBankAccount(val otherSession: FlowSession) : FlowLogic<Unit>() {
    @Suspendable
    override fun call() {
        logger.info("Starting ReceiveBankAccount flow...")

        val signedTransactionFlow = object : SignTransactionFlow(otherSession) {
            @Suspendable
            override fun checkTransaction(stx: SignedTransaction) = requireThat {
                val bankAccountState = stx.tx.outputsOfType<BankAccountState>().single()
                val result = getBankAccountStateByAccountNumber(bankAccountState.accountNumber, serviceHub)
                if (result != null) {
                    val linearId = result.state.data.linearId
                    throw IllegalArgumentException("Bank account $bankAccountState already exists with linearId ($linearId).")
                }
            }
        }

        subFlow(signedTransactionFlow)

        if (!serviceHub.myInfo.isLegalIdentity(otherSession.counterparty)) {
            subFlow(ReceiveFinalityFlow(otherSession))
        }
    }
}

InitiatorFlow中出错：

您必须将bankAccountState.verifier的密钥添加到命令中

在启动器流更改命令中，来自：

val command = Command(BankAccountContract.Add(), listOf(ourIdentity.owningKey))

你能用完整的stacktrace更新这个问题吗？还有，你用的是什么版本的Corda？嗨，Joel，我用的是Corda 4.0 RC 1；我的堆栈跟踪是在上面给出的，我使用的存储库是从RogerHmm做的现金发行人那里获取的，我看不出有什么错误。您可以发布流程的另一面（发起人运行的部分）吗？它与现金发行人存储库中的流程相同：

package com.r3.corda.finance.cash.issuer.common.flows.AddBankAccount

我已将其附在上面

val command = Command(BankAccountContract.Add(), listOf(ourIdentity.owningKey,bankAccountState.verifier.owningKey))
