tfcoremock_simple_resource.drift: Refreshing state... [id=cb79269e-dc39-1e68-0a9c-63cb392afda9] Note: Objects have changed outside of Terraform Terraform detected the following changes made outside of Terraform since the last "terraform apply" which may have affected this plan: # tfcoremock_simple_resource.drift has changed ~ resource "tfcoremock_simple_resource" "drift" { id = "cb79269e-dc39-1e68-0a9c-63cb392afda9" ~ string = "Hello, world!" -> "Hello, drift!" } This is a refresh-only plan, so Terraform will not take any actions to undo these. If you were expecting these changes then you can apply this plan to record the updated values in the Terraform state without changing any remote objects. ───────────────────────────────────────────────────────────────────────────── Saved the plan to: equivalence_test_plan To perform exactly these actions, run the following command to apply: terraform apply "equivalence_test_plan"
