Node.js Fabric NodeSDK addBlockListener给出错误，如果没有挂起的块，则失败

我正在尝试添加多个块侦听器，我的代码如下：

for (var i=0; i<channelid.length; i++) {
    let cid = channelid[i]
    let nextBlock = 1
    configPath = path.resolve(__dirname, `${cid}.nextBlock`)
    if (fs.existsSync(configPath)) {
        nextBlock = fs.readFileSync(configPath, "utf8")
    } else {
        fs.writeFileSync(configPath, parseInt(nextBlock, 10))
    }

    console.log(`Adding listener for channel ${cid}`)
    network = await gateway.getNetwork(cid)
    listener = await network.addBlockListener(
        async (event) => {
            await ProcessingMap.set(cid, event.blockData.header.number, event.blockData)
            console.log(`[${cid}] Added block ${event.blockData.header.number} to ProcessingMap`)
        },
        { startBlock: parseInt(nextBlock, 10) }
    )

    console.log(`[${cid}]: Listening for block events, nextblock: ${nextBlock}`)
    processPendingBlocks(ProcessingMap, cid, configPath)
};

然后此侦听器将无法拾取更多的块事件

如果我配置侦听多个通道，比如说

mychannel1

没有挂起的块，但是

mychannel2

有挂起的块，那么

mychannel1

侦听器将出现上述错误，并且

mychannel

中的后续块事件将不会被拾取<代码>mychannel2将不受

mychannel1

侦听器故障的影响

当我没有挂起的块要处理时，如何解决此错误

如何处理此错误场景，以便即使没有挂起的块，侦听器仍将成功添加并能够侦听后续事件

（我对NodeJS不是很在行，所以我希望通过简单的解释和示例代码来帮助我理解。）
