app.get('/edit/:id', function (req, res) {
db.collection('post').findOne({ _id: parseInt(req.params.id) }, function (error, result) {
console.log(result);
if (error) {
console.log('없는페이지입니다');
res.status(400).send({ message: '실패했습니다' });
}
res.render('edit.ejs', { post: result });
})
})
이런식으로 작성했는데
브라우저 창에

이렇게 출력되고 ,
콘솔창에는
GET http://localhost:8080/edit/200 500 (Internal Server Error)
이 메세지가 출력됩니다.
어떻게 해결해야할까요??
