我在nodejs中创建了firebase函数,并在firebase上部署了代码.该功能是在创建新用户时发送电子邮件.我现在丢失了代码.我们可以从firebase中提取代码吗？

以下是我的包json文件.我已经成功安装了node_modules.但得到错误:

"TypeError:无法读取未定义的属性'babel'"

在运行"webpack --watch"时.如果有人知道这一点,请告诉我.

我尝试向单个设备发送消息,即单个注册ID,它工作正常但是当试图添加多个注册ID时,它会出现"InvalidServerResponse"错误.例如,对于regTokens ='regId1'的作品; 但不适用于regTokens = ['regId1','regId2'];

var FCM = require('fcm-node');
// Add API Key
var fcm = new FCM('<server-key>');

exports.sendMessage = function (regTokens, messageToSend, callback) {
  var message = { //this may vary according to the message type (single recipient, multicast, topic, et cetera)
      to: regTokens,

      data: { 
        ar_message: messageToSend
      }
  };

    fcm.send(message, function(err, response){
        if (err) {
            console.log("Something has gone wrong!",err);
        } else {
            console.log("Successfully sent with response: ", response);
        }
        callback(err, 'Success');
      });
}

我正在使用Express Framework。我正在尝试从服务器发送非常大的数据。客户端收到200 OK状态，但没有数据。即使我从服务器发送内容长度标头，它也会给出错误ERR_CONTENT_LENGTH_MISMATCH。我回复的内容长度为2102619。

这是我用来发送响应的代码：

var rowNew = JSON.stringify(row); 
res.set({ 'Content-Length': rowNew.length }); 
return res.status(200).send(row); 

还尝试将时间限制增加到非常大：

server.timeout = 300000;
