This PR doesn't change the generated Terraform code, just the ID used for the Terraform state.

Can you add some description on the problem you're fixing? A before error and after would be ideal. Also some tests that show the problem before and after would be awesome.

[piperswe]

Added description and error. The existing tests should have been failing, I don't know why they wouldn't be.

the PR seems fine but i'm curious why this isn't failing in CI. what was the command invocation you were using here?
