Heroku ErrorPlanNotFound

Question

I'm trying to change my Heroku app region by following this official guide:

https://devcenter.heroku.com/articles/app-migration.

The problem is that, when I try to fork it at the very beginning using:

heroku fork --from keepmefit --to keepmefit-eu --region eu.

Heroku cli returns:

Forking keepmefit... done. Forked to keepmefit-eu
Setting buildpacks... done
Creating heroku-postgresql:dev on keepmefit-eu... !
 !    ErrorPlanNotFound

There was an error forking to keepmefit-eu.

In order to avoid being charged for any resources on keepmefit-eu, it is being destroyed...
Destroying app keepmefit-eu... done

I'm using the latest version of Heroku Cli 6.15.18-fdf2097 in Windows 10

Answer 1

Heroku ErrorPlanNotFound

That means Heroku showing Error:

Plan Not Found

Plan missing on the targeted app which already has the previous app.

It is not allowed on the free/unverified Heroku account here the documentation said

The forking user will be the owner of the app and responsible for any application charges. For this reason, your account needs to be verified if the application you're forking contains paid resources.

If your old app have any add- h plan then same plan need to have on target/new app

That's why you seeing the below message from CLI

In order to avoid being charged for any resources on keepmefit-eu, it is being destroyed...

Hope it helps
