位置2的JSON中的意外令牌

Question

我在这里找不到任何console.log。相反，我得到一个错误 Unexpected token in JSON at position 2

// api/favorite/:id
router.delete('/:id', (req, res) => {
  const { user } = res.locals
  console.log(user)
  if (user) {
    const { id } = req.params
    console.log(id)
    // USERS.find(({ id }) => id === user.id).favorites.filter(_id => _id !== id)
    res.status(200).json({ message: 'Job successfully deleted from favorites' });
  } else {
    res.status(403).json({ message: 'You are not authenticated' });
  }
});
