I'm trying to set up a Docusaurus site on a subdomain using cPanel with CloudLinux.

I have successfully installed Docusaurus inside a documentation folder within the subdomain.

I have also configured server.js to set up the Node.js application on cPanel.

However, when I try to access the site, I get a message related to the base URL.

Your Docusaurus site did not load properly.

A very common reason is a wrong site baseUrl configuration.

Current configured baseUrl = / (default value)

We suggest trying baseUrl = /

My site is on the root folder, so the baseUrl should remain as it is.

I've also noticed that if I try to open any JS file from the source code, I get a 500 error.

Additionally, trying to navigate to any item also returns a 500 error.

This is the content of my docusaurus.config.js:

// @ts-check
// `@type` JSDoc annotations allow editor autocompletion and type checking
// (when paired with `@ts-check`).
// There are various equivalent ways to declare your Docusaurus config.
// See: 

import {themes as prismThemes} from 'prism-react-renderer';

// This runs in Node.js - Don't use client-side code here (browser APIs, JSX...)

        darkTheme: prismThemes.dracula,
      },
    }),
};

export default config;

And here is the server.js I got from the suggestions.

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

// Serve static files from build directory
app.use(express.static(path.join(__dirname, 'build')));

// Handle all routes for client-side routing
app.get('/*', function(req, res) {
  res.sendFile(path.join(__dirname, 'build', 'index.html'));
});

app.listen(port, () => {
  console.log(`Server is running on port ${port}`);
});

Any suggestion of what to try next?
