Treeline：自定义机器上的错误无法读取属性＆＃39;模型＆＃39;未定义的

Question

使用自定义计算机时出现运行时异常问题：

我创建了一个自定义机器，它接受三个参数：一个数组，一个id和一个创建crud机器。它旨在循环遍历数组并使用数组元素和id调用机器，我使用循环机作为灵感但我得到了错误500.

这是我的机器：

module.exports = {
  "inputs": {
   "tags": {
   "id": "ce459bad-8a34-4d31-88d1-356bce99a427",
   "friendlyName": "tags",
   "description": "tags to be inserted",
   "typeclass": "array",
   "required": true,
   "addedManually": true
 },
 "questionid": {
   "id": "460b6d0a-296c-467a-b9f4-31849c414be9",
   "friendlyName": "question id",
   "description": "",
   "example": 1,
   "required": true,
   "addedManually": true
 },
 "worker": {
   "id": "d0dce741-1a7b-43c5-b45d-3b7cf11d2bf3",
   "friendlyName": "worker",
   "description": "",
   "typeclass": "machine",
   "required": true,
   "addedManually": true
    }
  },
"exits": {
  "error": {
    "example": undefined
  },
  "success": {
  "void": true,
  "friendlyName": "then",
  "variableName": "result",
  "description": "Normal outcome."
}
  },
   "defaultExit": "success",
  "fn": function(inputs, exits, env) {
  var async = require('async');

  if (!inputs.worker.inputs || typeof inputs.worker.inputs != 'object') {
    return exits.error("Worker misconfigured: no inputs object found");
  }
  var workerInputs = Object.keys(inputs.worker.inputs);
  if (workerInputs.length === 0) {
    return exits.error("Worker misconfigured: inputs object empty");
  }
  var loop = async.each;
  loop(inputs.tags, function(item, cb) {
    var config = {};
    config[workerInputs[0]] = item;
    config[workerInputs[1]] = inputs.questionid;
    config[workerInputs[2]] = 17;

    inputs.worker(config).exec(cb);
   }, exits);
   },
   "identity": "bulkcreateNtags"
  };

带错误的行是create_ntag.js：37代码：

env.sails.models.ntag.create(env.sails.util.objCompact(inputs)).exec(function(err, records) {
