MongoError:无效操作,批量操作无操作

我无法使用mongoose批量插入mongo.

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

// Define our results schema
var webSchema = new Schema({"abc" : String},{
  collection: 'web_v2'
});

MyApi.prototype.Webs= mongoose.model('Webs', webSchema);

resultData = [{"abc": "12121221"},{"abc": "44545"},{"abc": "545"}]

MyApi.prototype.Webs.collection.insert(resultData, function (err, myDocuments) {
  if (err) {
    console.log(err);
  } else {
    console.log("web inserted : " + myDocuments.result.n);
  }
});

我收到以下错误

有谁请让我知道我做错了什么.

您很可能正在尝试插入一个空数组.

以下是MongoDB Jira站点对此错误的引用

这可能是由于您的上一次insertMany尝试插入空数组[].我建议你在insertMany之前插入一个警卫.
