I got an ValidatorError when trying to add a new user using my API... I get the following error, even though the required fields are submitted. I can't really figure out why. I've added the relevant part of the code. Thanks.

enter image description here

Here is my code: userModel.js

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

const userSchema = new mongoose.Schema({
  name: {
    type: String,
    required: [true, 'Please tell us your name!'],
  },
  mobile: {
    type: Number,
    required: [true, 'Please tell us your mobile number!'],
    unique: true,
  },
  email: {
    type: String,
    unique: true,
    lowercase: true,
    validate: [validator.isEmail, 'Please provide a valid email'],
  },
  photo: {
    type: String,
    default: 'default.jpg',
  },
  role: {
    type: String,
    enum: ['user', 'guide', 'lead-guide', 'admin'],
    default: 'user',
  },
  password: {
    type: String,
    required: [true, 'Please provide a password'],
    minlength: 8,
    select: false,
  },
  passwordConfirm: {
    type: String,
    required: [true, 'Please confirm your password'],
    validate: {
      //This only works on create and save
      validator: function (el) {
        return el === this.password;
      },
      message: 'Passwords are not the same!',
    },
  },

  passwordChangedAt: Date,
  passwordResetToken: String,
  passwordResetExpires: Date,
  active: {
    type: Boolean,
    default: true,
    select: false,
  },

  referralCode: String,
  address: String,
  occupation: String,
  education: String,
  socialSiteLink: String,
  maritalStatus: String,
  religion: String,
  language: String,
  employmentStatus: String,
});

const User = mongoose.model('User', userSchema);
module.exports = User;

authControler.js

const User = require('../models/userModel');
const catchAsync = require('../utils/catchAsync');

exports.signup = catchAsync(async (req, res, next) => {
  const newUser = await User.create(req.body);

  res.status(201).json({
    status: 'success',
    data: {
      user: newUser,
    },
  });
});

catchAsync.js

module.exports = (fn) => {
  return (req, res, next) => {
    fn(req, res, next).catch(next);
  };
};
