关键错误插入到MongoDB使用node.js失败的一些对象没有任何键包含一个点

我有一个使用 Angular JS 绑定的web表单，并通过POST调用我的服务器代码中的路由，通过使用mongodb连接将插入到mongodb集合。

我尝试插入的对象是一个有效的Java Script对象，实际上，有时它只是插入ok，但有时Mongo会抱怨一个键包含一个点

这是Angular控制器内部的AJAX调用(它总是通过):

$.ajax({
    type:"POST",
    url:"/psychos",
    data:JSON.stringify(this.psycho)                
})

路由处理代码:

app.post("/psychos", function(request, response) {
    var psychologist = request.body
    console.log("We got via AJAX'n"+JSON.stringify(psychologist, undefined, 2))
    psicologosCollection.insert(psychologist, function(error, responseFromDB) {
        if (error) {
            console.log(error)
            response.send(responseFromDB)
        }
        else {
                console.log("Se ha insertado: "+ JSON.stringify(responseFromDB))
                response.send(responseFromDB)
        }
    })
})

我的服务器代码管理Passport认证，路由是在MongoDB连接上定义的。

这是我的整个服务器代码:

var express     =       require('express')
var mongodb     =       require('mongodb')
var mongoose    =       require('mongoose')

var Schema = mongoose.Schema
var userCredential = new Schema({
    username:   String,
    password:   String
},  {
    collection:     'members'
})
var userCredentials = mongoose.model('members', userCredential)

app.use(session({
    secret: 'ziKologiia',
    clear_interval: 900,
    cookie: { maxAge: 2 * 60 * 60 * 1000 },
    store: new MongoStore({
      db : mongoose.connection.db
    })
  }));

passport.serializeUser(function(user, done) {

passport.deserializeUser(function(user, done) {

        })
        app.get("/psychos/:id", function(request, response) {
            var id = new BSON.ObjectID(peticion.params.id)
            psicologosCollection.findOne( 
                                            {'_id':id},
                                            function(error,responseFromDB) { if (error) {response.send(responseFromDB)} response.send(responseFromDB)}
                                        )
