My apologies if this has been asked before but I can't seem to find anything on it. I am currently trying to run a GET operation but my code doesn't seem to work. I already have the simple set up done but when I click the button I created to request the data from a simple .JSON file I made I keep getting "0 documents retrieved". Could anyone assist with this? here is my code. Any and all help is appreciated. Thank you.

Handlebars -

<!DOCTYPE html>
    <title>Get Request</title>
    <h2>GET Request</h2S>
    <div class="results">
        {{#each data}}
        <p> {{first_name}} {{last_name}} </p>


<h2>GET Request</h2>
 <a href="/api/user"
 data-selector="results">Load user data</a> 
 <form action="/api/user" method="GET"></form>
<div class="results"></div>

JavaScript -

const express  = require("express")
const app = express();
const mongo = require('mongodb').MongoClient;
const assert = require('assert');
const url = 'mongodb://localhost:27017/test';
var bodyParser = require('body-parser'); 
var exphbs  = require('express-handlebars');
app.set('view engine', 'handlebars');
app.engine('handlebars', exphbs());

app.use(bodyParser.urlencoded({extended: true}));

app.get('/api/user', function(req, res) { 
    mongo.connect(url,{ useUnifiedTopology: true }, function(err, database) {
        const db = database.db('test');
            .toArray(function(err, result) { 
            if (err) { 
                throw err; 
            console.log(result.length + ' documents retrieved.'); 
            res.render('user', { data:result, layout:false})

app.get('*', function (request, response) {
    response.sendFile('./public/hello.html',{root: __dirname});

const port = 8900;
console.log(`Listening to server: http://localhost:${port}`)


    "id": 1,
    "name": {
        "first_name": "Robert",
        "last_name": "Swanson"
    "title": "Some Dude"

What I have tried:

So far I have tried a couple different things such as changing the names in the array and messing around with the expression names in the handlebars file but since VSC isn't throwing any errors I don't really know exactly where to start.
