The Ruby version you are trying to install does not exist on this stack. !

I have managed to change the stack, but only from a previously created app, but I can't find doing it with an app with auto deploy. Help please, I need an effective and easy way to manage sendgrid feedback.

I have this issue also. I cannot deploy any of the event-kit rails master or forks. I figured this would be a very popular way to monitor webhooks from sendgrid, is this project dead?

I replicated into my repo and degraded the stack in heroku to heroku-16 but i am facing the below issue while running the app.
