Class botman does not exist resolve(botman) in botman.php from template project when deploying to Heroku

[carlos-g-anguiano]

When running php artisan serve on mi local server, I'm able to connect to Facebook with my application without problem, but when deployed to Heroku and accessing the route ...routes/botman.php the Heroku logs show the following error:

I've seen similar problems with other classes such as View in Laravel, but I've tried from clean:cache, update my composer dependencies, adding a Facade BotMan in config/app.php array, again, with every modification it runs without problem in my pc but when accessing the route on Heroku it shows 500 internal server error message.

These are the versions of heroku and laravel I'm using:

• Laravel Framework 5.6.39
• PHP 7.2.8 (cli)

I am experiencing this same issue but on my local development environment.
