When a service registered in tfstate no longer exists, it results in an error during terraform plan

[taxintt]

Problem

After creating mackerel_service and mackerel_role by using Terraform, if these resources are manually deleted, terraform plan will fail to execute.

resource "mackerel_service" "app" {
  name = "app"
}

resource "mackerel_role" "bar" {
  service = mackerel_service.app.name
  name    = "bar"
}

# the case which service is manually deleted
Planning failed. Terraform encountered an error while generating this plan.

I don't verifiy this error for other resources, but it is possible that same error may occur.

The behavior of trying to re-create a resource when it does not exist as defined in Terraform have to be implemented on the Terraform provider side.
