Unable to create cloud private nat on gcp using google_compute_router_nat

[Pthuturkar]

TL;DR

Description: type parameter is not working in the resource google_compute_router_nat

Reference : https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/compute_router_nat#example-usage---router-nat-private

Expected behavior

Resource should be able to create private cloud nat on gcp

Observed behavior

error : Error: Unsupported argument
│
│ on .terraform/modules/cloud-nat-test/cloud_nat.tf line 20, in resource "google_compute_router_nat" "cloud_nat":
│ 20: type = "PRIVATE"
