Hyperlegder Fabric节点错误：2未知：流已删除

Question

我使用示例Fabcar/Javascript-low-level来调用 org1 中的多对等方（ peer1，peer2 和中的 peer3 org2 ）：

    const peer1 = fabric_client.newPeer('grpc://localhost:7051');
    console.log('Created client side object to represent the peer 1');
    const peer2 = fabric_client.newPeer('grpc://localhost:8051');
    console.log('Created client side object to represent the peer 2');
    const peer3 = fabric_client.newPeer('grpc://localhost:9051');
    console.log('Created client side object to represent the peer 3');

并创建请求

        const proposal_request = {
        targets: [peer1, peer2, peer3],
        chaincodeId: 'mychaincode',
        fcn: 'createAsset',
        args: ['Test'],
        chainId: 'mychannel',
        txId: tx_id
    };

然后选择event_hub为peer3

let event_hub = channel.newChannelEventHub(peer3);

但是我有错误：错误：2未知：流已删除到peer2，peer3。对等1 OK P / S：配置我的网络

peer1: host:
       -7051:7051
       -7053:7053
peer2: host:
       -8051:7051
       -8053:7053 
peer3: host:
       -9051:7051
       -9053:7053

请帮助我， 谢谢！
