Error: Provider produced inconsistent result after apply                                                                                               

When applying changes to google_project_service.enable_iamcredentials_service,
provider "registry.terraform.io/hashicorp/google" produced an unexpected new

I think this is somehow caused by the "project" key in the resource.

if I run it without, it works, e.g.:

{
    "resource": {
        "google_project": {
            "project": {
                "billing_account": "008F72-XXXX-XXXXX",
                "name": "Project Name",
                "org_id": "XXXXXX",
                "project_id": "a_project"
            }
        },
        "google_project_service": {
            "enable_cloudbilling_service": {
                // "project": "${google_project.project.id}",   REMOVE
                "service": "cloudbilling.googleapis.com"
            }
        }
    }
}

if I re-add, I get

  # google_project_service.enable_cloudbilling_service must be replaced
-/+ resource "google_project_service" "enable_cloudbilling_service" {
        disable_on_destroy = true
      ~ id                 = "a_project/cloudbilling.googleapis.com" -> (known after apply)
      ~ project            = "a_project" -> "projects/a_project" # forces replacement
        service            = "cloudbilling.googleapis.com"
    }

The correct attribute to call is ${google_project.project.project_id} instead of ${google_project.project.id}

This resolves my issue, but I will leave this bug on for someone else to decide whether this behaviour is insane or working as intended.

Below is what google_project provides. The formats of id and project are different. We should let google_project_service to accept both.

resource "google_project" "my_project" {
    id                  = "projects/myproject"
    name                = "myproject"
    project_id          = "myproject"
   .....
}
