Question

我在这里关注文档中的教程，我相应地编辑了文件并部署了节点，当尝试启动新流程时，出现以下错误

我正在从节点B运行以下命令

"start IOUFlow iouValue: 99, otherParty: "O=PartyB,L=New York,C=US"

，错误是：

IOUFlow代码：

@Suspendable
@Override
public Void call() throws FlowException {
    // We retrieve the notary identity from the network map.
    Party notary = getServiceHub().getNetworkMapCache().getNotaryIdentities().get(0);

    // We create the transaction components.
    IOUState outputState = new IOUState(iouValue, getOurIdentity(), otherParty);
    Command command = new Command<>(new TemplateContract.Commands.Action(), getOurIdentity().getOwningKey());

    // We create a transaction builder and add the components.
    TransactionBuilder txBuilder = new TransactionBuilder(notary)
            .addOutputState(outputState, TemplateContract.ID)
            .addCommand(command);

    // Signing the transaction.
    SignedTransaction signedTx = getServiceHub().signInitialTransaction(txBuilder);

    // Creating a session with the other party.
    FlowSession otherPartySession = initiateFlow(otherParty);

    // We finalise the transaction and then send it to the counterparty.
    subFlow(new FinalityFlow(signedTx, otherPartySession));

    return null;
}

cmd output

我该怎么办？

Answer 1

您正在尝试启动一个流程，其中节点B既是发起方又是目标方。这将在Corda 4.0中破坏FinalityFlow。

检查here以获得更多详细信息和解决方法。

Answer 2

您正在尝试打开与本地节点的会话。

A.k.a，您正在甲方的节点上运行流，并尝试向甲方发送交易。

尝试启动新的IOUFlow时出现流错误
