Error message while deleting google_kms_crypto_key resource

I am managing kms keys and key rings with gcp terraform provider

resource "google_kms_key_ring" "vault" { name = "vault" location = "global" } resource "google_kms_crypto_key" "vault_init" { name = "vault" key_ring = google_kms_key_ring.vault.self_link rotation_period = "100000s" # } 

When I ran this for the first time, I was able to create the keys and keyrings successfully and doing a terraform destroy allows the terraform code to execute successfully with out any errors.

The next time I do a terraform apply, I just use terraform import to import the resources from GCP and the code execution works fine.

But after a while, certain key version 1 was destroyed. Now everytime I do a terrafrom destroy, I get the below error

module.cluster_vault.google_kms_crypto_key.vault_init: Destroying... [id=projects/<MY-PROJECT>/locations/global/keyRings/vault/cryptoKeys/vault] Error: googleapi: Error 400: The request cannot be fulfilled. Resource projects/<MY-PROJECT>/locations/global/keyRings/vault/cryptoKeys/vault/cryptoKeyVersions/1 has value DESTROYED in field crypto_key_version.state., failedPrecondition 

Is there was way to suppress this particular error ? KeyVersions 1-3 are destroyed.

At present, Cloud KMS resources cannot be deleted. This is against Terraform's desired behavior to be able to completely destroy and re-create resources. You will need to use a different key name or key ring name to proceed.
