I have a Ruby on Rails app that I installed on a Shopify store. After installing it, I uninstalled the app from the store. Then, when I tried to reinstall the app, I encountered the error ‘このアドレスにはページがありません’ (This page does not exist). I’m unsure of the cause of this error as I didn’t experience it previously. Could you please help me understand the reason behind this error and provide guidance on how to resolve it? Thank you.
