Getting error data and salt arguments required on bcrypt? - node.js

Question

I am trying to save a user to MongoDB as follows, but I am getting the error bcrypt Error: data and hash arguments required. I have checked the same error question asked by other Dev on StackOverflow but it doesn't help. I have attached the codes of the model file and router file.
User Model file
const mongoose = require('mongoose');
const bcrypt = require('bcrypt');
const uSchema = new mongoose.Schema({
fullName: {
type: String,
required: true,
min: 4,
max: 30
},
email: {
type: String,
required: true,
trim: true,
unique: true,
index: true
},
hash_password: {
type: String,
required: true,
min: 6,
max: 12
},
role: {
type: String,
enum: ['user', 'admin', 'moderator'],
default: 'admin'
}
}, { timestamps: true });
uSchema.virtual('password')
.set(function (password) {
this.hash_password = bcrypt.hashSync(password, 10);
});
uSchema.methods = {
authenticate: function (password) {
return bcrypt.compareSync(password, this.hash_password);
}
}
module.exports = mongoose.model('User', uSchema);
User Router file
const express = require('express');
const router = express.Router();
const User = require('../models/user.model');
router.post('/login', (req, res) => {
});
router.post('/signin', (req, res) => {
User.findOne({ email: req.body.email })
.exec((error, user) => {
if (user) return res.status(400).json({
message: 'User already exists.'
});
const {
fullName,
email,
password
} = req.body;
const _user = new User({
fullName,
email,
password
});
_user.save((error, data) => {
if (error) {
return res.status(400).json({
message: 'Something went wrong'
});
} if (data) {
return res.status(201).json({
user: data
})
}
})
});
});
module.exports = router;

You can do it in the router file instead.
const bcrypt = require("bcrypt")
// ...
router.post('/signin', (req, res) => { // Change this to signup
User.findOne({ email: req.body.email })
.exec((error, user) => {
if (user) return res.status(400).json({
message: 'User already exists.'
});
const {
fullName,
email,
password
} = req.body;
const hashedPassword = bcrypt.hashSync(password, 10);
const _user = new User({
fullName,
email,
hashedPassword
});
_user.save((error, data) => {
if (error) {
return res.status(400).json({
message: 'Something went wrong'
});
} if (data) {
return res.status(201).json({
user: data
})
}
})
});
});
module.exports = router;
and delete the password virtual from the model.
