   To perform custom error-handling logic such as centralized logging you can add an "error" event listener:
 
 ```js
-app.on('error', function(err){
-  log.error('server error', err);
-});
+app.on('error', err =>

   If an error is in the req/res cycle and it is _not_ possible to respond to the client, the `Context` instance is also passed:
