  try {
    const response = await register(req.body);
    res.status(200).send(response);
  } catch (error) {
    res.status(400).send(error.message);
  }
});

app.post('/login', async (req, res) => {
  try {
    const response = await login(req.body);
    res.status(200).send(response);
  } catch (error) {

  }
});

app.post('/protected', authGuard, (req, res) => {
  res.status(200).send('This is a protected route');
