How to fix "User validation failed: password: Path `password` is required., email: Path `email` is required., name: Path `name` is required."

Question

I'm a beginner who starts to learn node.js. In the middle of the way, I got a problem with a notification like this

{
"errors": {
    "password": {
        "name": "ValidatorError",
        "message": "Path `password` is required.",
        "properties": {
            "message": "Path `password` is required.",
            "type": "required",
            "path": "password"
        },
        "kind": "required",
        "path": "password"
    },
    "email": {
        "name": "ValidatorError",
        "message": "Path `email` is required.",
        "properties": {
            "message": "Path `email` is required.",
            "type": "required",
            "path": "email"
        },
        "kind": "required",
        "path": "email"
    },
    "name": {
        "name": "ValidatorError",
        "message": "Path `name` is required.",
        "properties": {
            "message": "Path `name` is required.",
            "type": "required",
            "path": "name"
        },
        "kind": "required",
        "path": "name"
    }
},
"_message": "User validation failed",
"message": "User validation failed: password: Path `password` is required., email: Path `email` is required., name: Path `name` is required."}

This My User Model

const mongoose = require('mongoose')
const validator = require('validator')

const User = mongoose.model('User', {
    name: {
        type: String,
        required: true,
        trim: true
    }, 
    email: {
        type: String, 
        required: true,
        trim: true,
        lowercase: true,
        validate(value) {
            if (!validator.isEmail(value)) {
                throw new Error('Email is invalid')
            }
        }
    },
    password:{
        type: String,
        required: true, 
        minlength: 7,
        trim: true,
         validate(value){
            if (value.toLowerCase().includes('password')) {
                throw new Error('Password cannot contain "password"')
            }
        }
    },
    age: {
        type: Number, 
        default: 0,
        validate(value) {
            if (value < 0 ){
                throw new Error('Age must be a positive number')
            }
        }
    }
})

module.exports = User

With this user route

const express = require('express')
require('./db/mongoose')
const User = require('./models/user')
const Task = require('./models/task')

const app = express()
const port = process.env.PORT || 3000

app.use(express.json())

app.post('/users', async (req, res) => {
    const user = new User(req.body)

    try{
        await user.save()
        res.status(201).send(user)
    } catch (e) {
        res.status(400).send(e)
    }
})



app.listen(port, () => {
    console.log('Server is up on port' +port)
})

Does anyone understand why it would be happening?

Hope I get the answer in this forum to continue my study. Thank you in advance for your help guys. Really appreciate it.

Answer 1

As you have defined all these fields as required:true in your schema that's why its happening, you have to provide values to these fields i.e. while testing your api do fill these fields with some value in body.

Answer 2

common mistake for this error: rechecks your input field name same as you define in schema ...

Answer 3

In your "Postman" before sending, change to "body" and then to "raw" module and at the end where "Text" is, change to "JSON" so your code will work.

Answer 4

Try this, In my case I used this

app.use(express.json())

below

app.use("/users",usersController);

So, this cause the problem as my data is not parsing properly.

  const express = require("express");
    const app = express();
    const connect = require("./config/db");
    const usersController = require("./controller/user.controller");
    
    app.use(express.json());
    
    app.use("/users",usersController);
    
    
    
    const start = async () => {
      await connect();
      app.listen(2000, async function () {
        console.log("listening on port 2000");
      });
    };
    module.exports = start;
