Question

我查看了这里的每篇文章，但没有任何匹配。

使用最新资源

"mongoose": "^4.8.1"
"bluebird": "^3.4.7"

使用蓝鸟的猫鼬方式

mongoose.Promise = require('bluebird');

错误发生在＆＃34; respHelper.resp ...＆＃34;呼叫 Trader.Model是mongoose模型的地方＆＃34; TraderModel = mongoose.model（＆＃39; Trader＆＃39;，Trader）;＆＃34;

TraderModel.findOne({_id: req.account.traderid})
.then(function(trader) {
  respHelper.resp(200, res, {trader: trader});
  return null
})
.catch(function(error) {
  eLogger.error("Could not get Trader", ERRORS.ERR_DATABASEERROR, [], {accountid: req.account._id, traderid: req.params.traderid, exception: error});
  respHelper.respErr(500, res, ERRORS.ERR_DATABASEERROR);
  return null;
});

完整堆栈跟踪：

编辑：添加了TraderModel

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var Trader = new Schema({
  // Trader profile datas
  companyName: String,
  ustIdent: String,
  plz: String,
  city: String,
  country: String,
  street: String,
  streetNumber: String,
  contactPersonTechnical: String,
  contactPersonBilling: String,
  email: String,
  // Accounts für den Trader
  accounts: [
    {
      accountid: {type: Schema.Types.ObjectId, ref: 'Account'},
    // Rechte
      rights: {
        allowAddAccount: Boolean
      }
    }
  ],
  // Kunden des Traders
  customerids: [{type: Schema.Types.ObjectId, ref: 'Customer', index: true}],
  // Sub-Trader (untergeordnet)
  traderids: [{type: Schema.Types.ObjectId, ref: 'Trader', index: true}],
  // Haupttrader (übergeordnet)
  traderid: {type: String, trim: true, index: {unique: true}},
  created: {type: Date, default: Date.now()}, // im system angelegt am....
  changed: {type: Date, default: Date.now(), index: true} // geändet am...
});
Trader.set('toJSON', {getters: true, virtuals: false, depopulate: true});

Trader.methods.filterForPublic = function() {
  var tmpJson = this.toJSON();
  var publicData = {
    id: tmpJson._id,
    traderid: tmpJson.traderid,
    companyName: tmpJson.companyName,
    ustIdent: tmpJson.ustIdent,
    plz: tmpJson.plz,
    city: tmpJson.city,
    street: tmpJson.street,
    streetNumber: tmpJson.streetNumber,
    country: tmpJson.country,
    contactPersonTechnical: tmpJson.contactPersonTechnical,
    contactPersonBilling: tmpJson.contactPersonBilling
  };
  return publicData;
};

var TraderModel = mongoose.model('Trader', Trader);

很抱歉盲目看到：/

原因在一个完全不同的地方。 Shoudl在堆栈跟踪方面看起来更好。

从上一次活动开始：在d：\ Projects \ work \ UCConnectAPI \ server \ app \ lib \ apitokenmanager.js：53：43 在d：\ Projects \ work \ UCConnectAPI \ server \ node_modules \ jsonwebtoken \ verify.js：27：18

＆＃34;简单的例子是一个承诺是在一个处理程序中创建的但是没有从它返回＆＃34;
