ытался перейти с Corda Server на Spring Boot. Я ссылался на проект Джоэла (официальный представитель Corda) в Kotlin, но получил это исключение при попытке использовать rpcOps.

RPCClientProxyHandler.artemisMessageHandler - RPC reply arrived to unknown RPC ID RpcRequestId(toLong=2111196934580277300), this indicates an internal RPC error.

Ниже мой RPConnector:

private CordaRPCOps rpcOps;

    @PostConstruct
    private void init() {
        System.out.println("RPConnector [host=" + host + ", username=" + username + ", password=" + password
                + ", rpcPort=" + rpcPort + "]");
        NetworkHostAndPort rpcAddress = new NetworkHostAndPort(host, Integer.valueOf(rpcPort));
        CordaRPCClient rpcClient = new CordaRPCClient(rpcAddress);
        CordaRPCConnection rpcConnection = rpcClient.start(username, password);
        rpcOps = rpcConnection.getProxy();
    }

    public CordaRPCOps getRPCops() {
        return rpcOps;
    }

Соединение происходит успешно, но когда я пытаюсь использовать разъем RPC, я получаю следующую ошибку: Ниже мой контроллер. Когда я пытаюсь получить все узлы, я получаю ошибку:

@Autowired
private RPConnector rpcOps;
private final List<String> serviceNames = ImmutableList.of("Controller", "Network Map Service");

@GetMapping("/allnodes")
@Produces(MediaType.APPLICATION_JSON)
public Map<String, List<CordaX500Name>> getAllNodes() {
    List<NodeInfo> nodeInfoSnapshot = rpcOps.getRPCops().networkMapSnapshot();
    return ImmutableMap.of("allnodes",
            nodeInfoSnapshot.stream().map(node -> node.getLegalIdentities().get(0).getName()).filter(
                    name -> !name.equals(rpcOps.getRPCops().nodeInfo().getLegalIdentities().get(0).getName())
                            && !serviceNames.contains(name.getOrganisation()))
                    .collect(toList()));
}

Спасибо.

Обновление при ошибке, исключение нулевого указателя:
