How to handle uncaught errors?

[Foo JH]

It is not clear to me with the current version of restify how to handle runtime errors such as throw new Error(). I tried the following code but it did not catch:

server.on('uncaughtException', (req, res, route, err) => {

err.body = 'i caught it!';

res.send(500,err);

});

Can anyone advise?
