Mongoose is updating wrong object in mongodb

Question

I have a problem saving the data in mongodb.

Context

I have an express api that listens to requests to save the data to the mongodb an application sends. This data is related to APP page views, clicks, etc.

add.js

This is the file responsible for updating the field dataEvent: {type: Array, require: true} in the Mongoose model. On this route I look for the id that is sent by the application and push this array.

require('../models/Event')

const express = require('express')
const router = express.Router()
const mongoose = require('mongoose')
const Event = mongoose.model("event")
const { validateToken } = require('../helpers/validateToken')
const {Console} = require('../providers/console-provider')
const {response} = require('../helpers/response-helper')


router.put('/', (req, res) => {
    let id = req.body.id
    data = req.body.body
    console.log(data)
    if(id != undefined & data != undefined){
    Event.findOne({_id: id}).then(async (doc)=>{
        await doc.dataEvent.push(data)
        doc.save().then(async (s)=>{
            console.log("Add com  sucesso")
            console.log(s)
            await response(200, "Evento adicionado com sucesso!", res)
        }).catch(()=>{
            res.status(500)
            res.send({error: true, info: "Não foi possível adicionar o     evento!"})
        })


    }).catch((err)=>{
            console.log(err)
            res.status(500)
            res.send({error: true, info: "Não foi possível adicionar o         evento!"})

    })
}else{
    console.log("Dados da requisição inválidos!")
    res.status(500)
    res.send({error: true, info: "Dados inválidos"})
}
})

module.exports = router

Console

In the console this result is displayed (it has some confidential data, but the dataEvent is displayed, with the two records):

Add com  sucesso
{ dataEvent:
   [ { type: 'view', page: 'login-page' },
     { type: 'click', page: 'doctor-list' } ],
  _id: 5dc030cba1752e1b08847884

The problem

The problem in all this is that in mongodb the record that is pushed is not saved! It should have the record added in the file path add.js

server.js

This is the server file

require('dotenv/config')

const {
    express,
    http,
    providers: {
        consoleProvider: {
            Console
        }
    },
    routes: {
        init,
        update,
        add
    },
    mongoose,
    bodyParser,
    cors,
    verifyToken: {
        validateToken
    }
} = require('./import')

const app = express()
const c = Console

if (process.env.ENV == "PROD") {
    bd_host = process.env.BD_PROD
} else if (process.env.ENV == "TEST") {
    bd_host = process.env.BD_TEST
} else {
    bd_host = process.env.BD_DEV
}
app.use(cors())
app.use(bodyParser.urlencoded({ extended: true }))
app.use(bodyParser.json())

mongoose.connect(bd_host, { useNewUrlParser: true, useUnifiedTopology: true             }
    .then((success) => { Console("Banco de dados conectado!") })
    .catch((error) => { Console("Erro ao se conectar com a base de dados!")     })

app.use('/init', validateToken, init)
app.use('/add', validateToken, add)
app.use('/update', validateToken, update)

app.use((err, req, res, next) => {
    console.log(err)
    res.status(500)
    res.json({ error: true, info: "Erro interno no servidor" })
})

app.listen(
    process.env.PORT,
    () => {
        Console("Servidor rodando na porta: " + process.env.PORT)
    }
)

Situation found

When the app sends a request to the route /init it generates an id where it is stored on the device. But when the request is made on the route /add It updates a previous id. I’ll show in the photo:

Answer 1

I don’t know if you have any server configuration file, but one of the things that might be happening is the express doesn’t understand req.body, in case you haven’t put another place, add that below express require;

const express = require('express')
express.use(express.json())
const router = express.Router()

and checks if req.body is bringing the data from the front.

tries to change doc.save() to doc.update();
