service_accounts_iam doesn't work with computed values

[red8888]

TL;DR

You already fixed this here: https://github.com/terraform-google-modules/terraform-google-iam/issues/75\

You need to apply the same fix to this module

Expected behavior

Works with computed values

Observed behavior

│ 50: for_each = module.helper.set_additive │ ├──────────────── │ │ module.helper.set_additive is a set of dynamic, known only after apply │ │ The "for_each" set includes values derived from resource attributes that cannot be determined until apply, and so Terraform cannot determine the full set of keys that will identify the instances of │ this resource.

Terraform Configuration

module "my_acct" {
  source           = "terraform-google-modules/iam/google//modules/service_accounts_iam"
  service_accounts = [data.google_service_account.my_acct.email]
  project          = var.project_id
  mode             = "additive"
  bindings = {
    "roles/iam.serviceAccountTokenCreator" = [
      "serviceAccount:${google_service_account.aaaa.email}",
    ]
    "roles/iam.serviceAccountUser" = [
      "serviceAccount:${google_service_account.aaaa.email}",
    ]
  }
}

Terraform Version

Terraform v1.9.5

I faced the same issue and couldn’t use the service_accounts_iam module.

So, I opted to use google_service_account_iam_member directly.
