It is much easier to write
```javascript
.catch(next)
```

Since you are not doing any error handling here, there is no need for the creation of an extra scope.  Since this is an anonymous function, it will be created every time the route is called, executed, then discarded.

We may change this practice in the future and add in error handling directly to each route, but for now, using `next` immediately passes the error to a global error handler which can decide what to do with it.
