code is in directory: /home/routes/home.js -


const express = require('express');
const router = express.Router();

router.get('/', (req, res) => {
  res.sendFile(__dirname + './../site/index.html');
});

module.exports = router;

file “index.html” is in /home/site/index.html

this should be just /.
