My web app throws a 500 Internal Server Error despite the server running fine. No clear logs indicate the issue. The backend is in Node.js with Express.js.

app.post('/submit', async (req, res) => {
    let data = await processData(); // Possible async issue?
    res.send(data);
});

Could it be an async error or a missing middleware? Looking to hire developers in the USA who specialize in backend debugging.
