Estou tentando rodar uma aplicacao no heroku, mas ele nao consegue encontrar as pastas pelo consign. Detalhe, que a aplicacao localmente roda perfeitamente, mas ao subir ela nao funciona.

Meu consign: consign({cwd: 'app'}) .include('controllers') .then('persistencia') .then('routes/auth.js') .then('routes') .into(app);
