Auth0用户注册后Webtask保存到mongodb

Question

我想将Auth0用于我的项目，因为我想使用他们的服务来保存用户和＆amp;密码，我希望能够将至少用户数据导出到我的mongodb数据库。

Auth0有一些用户注册挂钩，一旦用户成功注册就会被触发，所以我想执行我的脚本将该用户保存到我在mlab上托管的mongodb数据库。

现在，我以前从未使用过Webtask，但我没有得到它......有人可以帮我实现目标吗？

干杯

编辑：这就是我现在使用的：

var mongoose = require("mongoose");
mongoose.connect("mongodb://username:password@ds115131.mlab.com:15131/dbname");

var UserrSchema = new mongoose.Schema({
  username: String,
  email: String,
})

module.exports = mongoose.model("Userr", UserrSchema);

module.exports = function (user, context, cb) {
  var username = user.username;
  var email = user.email;

  var newUserr = {
    username,
    email,
  };
  Userr.create(newUserr, function (err, newlyCreated) {
    if(err) return (err);
    nnewlyCreated.save();
  });
};

使用此脚本时出现此错误：
