Can't save data into MongoDB server using Mongoose

Question

I'm trying to integrate a database into my DiscordBot app and currently having a problem with inputting new user into MongoDB using Mongoose. The console also show no err at all.

const mongoose = require('mongoose')
const User = require('../models/userModels')

module.exports = message => {
    User.findOne({userID:message.author.id}, (err,user)=>{
        if(user == null){ //Create new db collections if none was found
            const user = new User({
                _id: mongoose.Types.ObjectId(),
                userID: message.author.id,
                username: message.author.username,
                role: ["default"],
                balance: 0,
                level: 1,
                exp: 0,
                lastAttendance: message.createdAt
            })

            user.save()
            .then(result => {
                console.log(result)
                message.reply("Information saved")
            })
            .catch(err => console.log.err)

        }
}

This is my model code:

const mongoose = require('mongoose')
const Schema = mongoose.Schema

var userSchema = new Schema({
    _id: Schema.Types.ObjectId,
    userID:{type: String, unique:true, required:true},
    username: String,
    balance:{type: Number, require:true},
    role: {type:String, enum: ['default','admin']},
    level:{type: Number, require:true},
    exp:{type: Number, require:true},
    lastAttendance: Date
})

module.exports = mongoose.model('Users', userSchema)

could you console.log(user) before the if condition, to check if the user exists or not? also console.log(message.author) to check its contents — Mohammed Yousry

The reason why you are not getting error logs is because of the console.log syntax in the catch statement is wrong. Change console.log.err to console.log(err)

The type defined for role in the userSchema is String and you are passing it as array role: ["default"]. You need to change this to role: "default".

Also on success, if you are trying to set the key reply to the message object with value "Information saved" then you should replace message.reply("Information saved") with message.reply = "Information saved"

Problem solved, thanks!! By the way, message.reply was a function from discord.js module, so I'm ok with that part
