Hi @AbelHristodor

Since this is a Terraform Google provider issues hub you need to share your Terraform code to see what is happening. Please share it to check what is happening

Thanks!

Confirmed issue with the following example:

Initial code:

resource "google_artifact_registry_repository" "private_repo_22170" {
  location                = "us-central1"
  project                 = "my-project"
  repository_id           = "private-repo-22170"
  description             = "something"
  format                  = "docker"
  cleanup_policy_dry_run  = false
 
  docker_config {
    immutable_tags = false
  }

  cleanup_policies {
    id     = "dev-delete-older-15-days"
    action = "DELETE"

    condition {
      tag_state    = "ANY"
      tag_prefixes = ["dev-"]
      older_than   = "1296000s"
    }
  }
}

Final code:

resource "google_artifact_registry_repository" "private_repo_22170" {
  location                = "us-central1"
  project                 = "my-project"
  repository_id           = "private-repo-22170"
  description             = "something"
  format                  = "docker"
  cleanup_policy_dry_run  = false
 
  docker_config {
    immutable_tags = false
  }

  cleanup_policies {
    id     = "dev-delete-older-30-days"
    action = "DELETE"

    condition {
      tag_state    = "TAGGED"
      older_than   = "864000s"
    }
  }
}

Error: The terraform-provider-google-beta_v6.27.0_x5 plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.
