How do I enable Google App Engine API with Terraform? I'm attempting to enable the AppEngine service via Terraform but I'm getting an error:
Error: Error creating App Engine application: googleapi: Error 403: App Engine Admin API has not been used in project &lt;redacted&gt; before or it is disabled. Enable it by visiting https://console.developers.google.com/apis/api/appengine.googleapis.com/overview?project=&lt;redacted&gt; then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry., accessNotConfigured

As far as I know all that should be required to enable the service/API is:
// Enable AppEngine API - required to automagically create datastore
resource &quot;google_project_service&quot; &quot;appengine_api&quot; {
  project = var.project
  service = &quot;appengine.googleapis.com&quot;

  disable_dependent_services = true
}
The terraform service account was located in a separate project and the API needed to be enabled for appengine in the account the Terraform service account runs in even though it was creating a resource in an another project.
