check the path of index.html com your foldering should be like this:

if your foldering like this:

user path module and join path so just try

const path = require('path');
const express = require('express');
const app = express();
const port = 3000 || process.env.PORT;

app.get('/', (req, res) => {
    // res.sendFile(__dirname + '../Structures/index.html');
