Hello, i am trying to use Method-based middleware but i get the following error

next is not a function

Here is the code:
const fetchUser = (req, res, next) => { next(); });
app.get('/comment/:id', fetchUser, (req, res) => { res.send(req.params.id); });

The Generic Middleware approach works fine. Do you have any clue about this ? Thanks
