axios get request to mongodb returns empty data

I make an axios request from the frontend through node to a Mongodb database requesting a userName based on userId. The request comes back as having been made, but no data is returned.

This is the Mongodb users collection:

{
    "_id" : ObjectId("5e1b46cb2e6f4c98904598b0"),
    "userId" : "[email protected]",
    "userName" : "Fool",
}

This is the 'Users' schema file

users model: 

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

const UserSchema = new Schema({
    userId: String,
    userName: String,
  });

module.exports = mongoose.model('Users', UserSchema);

This is the backend request:

backend: 
const express = require('express');
const UserRoute = express.Router();
const Users = require('../Models/UserModel');

UserRoute.route('/fetchUserName').get(function (req, res) {
  Users.find({userId: req.query.userId}, {userName: 1})
    .exec(function (err, user) {
    if (err) {
      console.log(err);
      res.json(err);
    } else {
      console.log(user.data);
      res.json(user.data);
    }
  });
});

Here is the actual request from the frontend:

getUserName = () => 
 axios.get('http://localhost:4000/Users/fetchUserName', {params: {userId: '[email protected]'}})
   .then(res => {
       return res.data;
   });
};

res.data is returned as an empty string.

Any ideas why the request does not work.

The userId should probably send as a string. So either:

const params {
  userId: '[email protected]'
}
axios.get('http://localhost:4000/Users/fetchUserName', { params })

or

axios.get('http://localhost:4000/Users/fetchUserName', {params: {userId: '[email protected]'}})
