Hosting on heroku

Hi ,
I am working on a tutorial to host n8n on heroku https://medium.com/@defivc/host-your-own-zapier-on-heroku-43b1b8efff69

In the last step when I check the deployment status, I am unable to see the app running on heroku, I instead see the default heroku app screen as follows

Welcome to the community @neuromancer1729!

Thanks a lot for working on this! Sadly did I never use Heroku so I can not tell you what exactly is going wrong. Expect, however, that the issue is related that it starts on a different port than you expect. n8n runs by default on port 5678 but you do not mention it anywhere in your guide. So do not know how Heroku would know about that and I would say it can not work.
If that is not the problem or something else is still not working, it is maybe a good idea to check out the following documentation and guides. Maybe reading through them helps you figure out what could be missing or is wrong:
https://docs.n8n.io/#/configuration

Additionally is here also the default docker-compose setup. Maybe you find also something there that helps:
https://docs.n8n.io/#/server-setup
