AI Summary: The application is critically failing to start because `server.js` attempts to reference and mount three non-existent route files: `frontend.js`, `support.js`, and `upload.js`. This issue prevents the server from initializing, leads to 500 errors, and results in a poor user experience. The proposed solution involves creating these missing files with proper Express Router implementation, error handling, and intentionally designed vulnerabilities for CTF challenges.
