Question

An AI agent wrote this Node.js webhook handler that charges a customer and then logs the event. It says the try/catch makes it robust. Review it.

typescript
async function handleWebhook(req: Request, res: Response) {  const { customerId, amount } = req.body;  try {    chargeCustomer(customerId, amount);        // returns a Promise    await db.insert('charges', { customerId, amount, status: 'ok' });    res.status(200).json({ ok: true });  } catch (err) {    await db.insert('charges', { customerId, amount, status: 'failed' });    res.status(500).json({ ok: false });  }}

What breaks, and what symptom shows up in prod?

What a strong answer looks like

Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it — tests, edge cases, reading critically — and how you’d re-prompt or decompose to get it right.
