Error-handling - 404 for remoteMethods

I have been able to easily set up a basic node.js api with the help of strongloop. I have been able to add custom routes using remoteMethods. However, I am a bit confused in setting up 404 for those routes. I have one route for model category named mature that takes one argument(categorId) and fetches all games under that category that have boolean value set to true for mature. The endpoint url is: http://localhost:3000/api/Categories/1004/games/mature. If I place a non existent categorId, it breaks. What would be the best way to setup routes to handle 404 for errors? For example, display "no such category id". Github REPO

common/models/category.js

Category.mature = function(id, limit) {
    var app = this.app;
    var Games = app.models.Games;
    Category.findById(id, {}, function(err, category){
        if (err) return callback(err);
        //set limit
        if (limit && limit > 5){
          limit = 5;
        }else if(limit === undefined){
          limit = 5;
        }
        Games.find({
            "where": {
                categoryId: id,
                mature: true,
                gameId: {gt: hashids.decode(after)}
            },
            "limit": limit
        }, function(err, gameArray) {
            if (err) return callback(err);
            callback(null, gameArr);
        });
    )};
    Category.remoteMethod(
    'mature', {
        accepts: [
            {arg: 'id', type: 'number', required: true},
            {arg: 'limit',type: 'number',required: false}
        ],
        // mixing ':id' into the rest url allows $owner to be determined and used for access control
        http: {
            path: '/:id/games/mature',
            verb: 'get'
        },
        returns: {
            root: true,
            type: 'object'
        }
    }
);

};

Set err.statusCode to 404 before you call callback(err):

if(!category) {
  var err = new Error('Category ID ' + id + ' does not exist.');
  err.statusCode = 404;
  callback(err);
}

This will result in:
