Reduce/mute node.js stack trace

If I try running localhost:3000/foo/bar, I'm supposed to get a 404 error. I do get that error and a huge stack trace. Currently I don't need such a long stack trace, is there a way to mute it?

if (!foo) {
    var err = new Error('404');
    err.status = 404;
    return next(err);
  }
  res.render('bar/foo', {
    foo: foo.toJSON()
  });
