我正在将Web应用程序部署到heroku。但是我遇到了本地未发生的错误。 MongoDB版本:3.6.3 引发的错误是:

我正在使用Node.js + Express和monogoose,连接到MongoDB Atlas。

我不确定该错误的原因。我已经审查了路线,猫鼬模型以及与BD的连接。但我找不到问题的根源

代码。 数据库连接:

const mongoose = require('mongoose');
const { mongodb } = require('./keys');
const options = {
  useNewUrlParser: true,
  useCreateIndex: true,
  useFindAndModify: false,
  autoIndex: false, 
  reconnectTries: Number.MAX_VALUE, 
  reconnectInterval: 500, 
  poolSize: 10, 
  bufferMaxEntries: 0,
  connectTimeoutMS: 10000, 
  socketTimeoutMS: 45000, 
  family: 4 
};

// mongodb.URI: mongodb+srv://xxxx:xxxx@xxxx-rbrmd.mongodb.net/test?retryWrites=true
connectTo=()=>{
  mongoose.connect(mongodb.URI, options)
    .then(db => console.log('DB is connected'))
    .catch(err => console.log("Error: " + JSON.stringify(err)));

}

connectTo()

module.exports = connectTo;

型号:

const mongoose = require('mongoose');

const { Schema } = mongoose;

const listEquipos = new Schema({
  nombreEquipo: String,
  thumbnail: String
});
const listaDeEquipos =mongoose.model('equipos_ligamx', listEquipos);

const partidos_pendientes_LigaMx = new Schema({
  equipoLocal: String,
  thumbnailLocal: String,
  equipoVisitante: String,
  thumbnailVisitante: String,
  fecha: String,
  hora: String
});
const partidosPendientesLigaMx = mongoose.model('partidos_pendientes_ligamx', partidos_pendientes_LigaMx);

const partidos_jugados_LigaMx = new Schema({
  equipoLocal: String,
  thumbnailLocal: String,
  equipoVisitante: String,
  thumbnailVisitante: String,
  year: String,
  resultado: String,
  ganador: String
});
const partidosJugadosLigaMx = mongoose.model('partidos_jugados_ligamx', partidos_jugados_LigaMx);

module.exports = {
  listaDeEquipos,
  partidosPendientesLigaMx,
  partidosJugadosLigaMx
}

还有我存放在BD中的另一个文件:

const puppeteer = require('puppeteer');
const mongoose = require('mongoose');
const { listEquiposLigaMx, partidosPendientesLigaMx, partidosJugadosLigaMx } = require('../../models/liga-mx')
var fs = require("fs");
var url = 'https://www.marca.com/claro-mx/futbol/liga-mx/clausura/calendario.html'

getPartidosPendientesLigaMx=()=>{

puppeteer.launch()
.then(async (browser) => {
    const page = await browser.newPage();
    await page.goto(url);
    let equipo = await page.evaluate(()=>{

        const img_local = [
            ...document.querySelectorAll('.local figure img')
        ]

        const img_visitante = [
            ...document.querySelectorAll('.visitante figure img')
        ]

        const equipo_local = [
            ...document.querySelectorAll('.local span')
        ].map((equipoLocal)=> equipoLocal.innerText);

        const equipo_visitante = [
            ...document.querySelectorAll('.visitante span')
        ].map((equipoVisitante)=> equipoVisitante.innerText);

        const fecha = [
            ...document.querySelectorAll('.resultado .fecha')
        ].map((fecha)=> fecha.innerText);

        const hora = [
            ...document.querySelectorAll('.resultado .hora')
        ].map((hora)=> hora.innerText);
        const size = equipo_local.length;
        var resize = equipo_local.length-fecha.length-1;
        var indicador = -1;
        var date = new Date()
        var day = date.getDate()
        var month = date.getMonth()


        return equipo_local.map((item, index)=>{
            if(resize>index-1 && resize<img_local.length-1){
                resize++
                indicador++
                return(
                    ({
                        equipoLocal: img_local[resize].alt,
                        thumbnailLocal: img_local[resize].src,
                        equipoVisitante: img_visitante[resize].alt,
                        thumbnailVisitante: img_visitante[resize].src,
                        year: 2019,
                        fecha: fecha[indicador],
                        hora: hora[indicador]

                    })
                )
            }
        })
    })

    var equipoParse = equipo.filter(function (el) {
        return el != null;
      });

    partidosPendientesLigaMx.insertMany(equipoParse, function(err) {
        if (err) {console.log("El error papu: ",err)}
        console.log("Saved!")

    });
    await browser.close();
  }).
  catch((err)=> console.log('> Error: ', err))
}
