Express js - Error handling in middleware

I have a route 

 app.get("/some/url/", function(req, res){ res.sendStatus(404) })

I am trying to handle or catch this 404 in express error handling middleware and it is not working

 app.use(function(err, req, res, next){do something here})

Any help how do i capture the error thrown by route in the middleware.

app.get("/some/url/", function(req, res) {
    // Generate Error yourself.
    throw new Error("Generated Error.");
});

// global error handler
app.use(function(err, req, res, next) {
    console.dir(err);
    
    if(err) {
        // Your Error Status code and message here.
        res.status(500).send('Something broke!');
    }

    // Send Some valid Response
});
