Heroku finds that there is a gulpfile in your project and expects there to be a heroku:production task (in the gulpfile). So all you need to do is register a task that matches that name:
gulp.task("heroku:production", function(){
console.log('hello'); // the task does not need to do anything.
});
This is enough for heroku to not reject your app.
