Your route should be looks like:

 http://localhost:3000/profile/56e2c3c2cdde3f64302ac154

It is automaticaly set req.params.id.

There is a difference between Path param and Query param . The Url you have defined

/profile/:id

Says to the routing framework that , I expect id as Path param i.e part of the resource path . But in the url request you made

 http://localhost:3000/profile?id=56e2c3c2cdde3f64302ac154

You are sending id as query param . So the routing framework is unaware of the url with id as a query param . Hence it returns a 404 meaning "the server could not find what was requested" .
