I’m trying to get a legacy Ruby on Rails app running on the App Platform - it’s currently using ruby 2.3.1, which I realise is fairly old now - upgrading is on the cards, but ideally I’d like to get it running with this version first.
I deploy, and see this message:
The Ruby version you are trying to install does not exist on this stack. You are trying to install ruby-2.3.1 on heroku-18. Ruby ruby-2.3.1 is present on the following stacks: - cedar-14 - heroku-16
Is it possible to specify the stack somehow? I can’t seem to find a configuration option for it.
Many thanks for any help!
