Hi @clearclaw!

After trying to replicate this issue the result was successfully without errors. I suggest you to check your private configurations and try the next configuration if you are using google and Google beta providers, or check this provider guide and this terraform registry example:

terraform {
  required_providers {
    google = {
      source  = "hashicorp/google-beta"
      version = "5.34.0"
    }
  }
}

resource "google_kms_key_ring" "kms_key_ring_18500" {
  name     = "kms-key-ring-18500"
  location = "us-central1"
}

resource "google_kms_crypto_key" "kms_crypto_key_18500" {
  key_ring = google_kms_key_ring.kms_key_ring_18500.id
  lifecycle {
    prevent_destroy = false
  }
  name            = "kms-crypto-key-18500"
