[kwohlfahrt]

Terraform Core Version

1.9.8

Terraform Vault Provider Version

4.4.0

Vault Server Version

1.18.0

Affected Resource(s)

vault_aws_auth_backend_config_identity

Expected Behavior

The following resource should apply:

resource "vault_aws_auth_backend_config_identity" "example" {
  backend      = "aws"
  iam_alias    = "canonical_arn"
  iam_metadata = ["canonical_arn", "account_id"]
}

Actual Behavior

I see the error below:

│ Error: expected iam_alias to be one of ["role_id" "unique_id" "full_arn"], got canonical_arn
│ 
│   with vault_aws_auth_backend_config_identity.example,
│   on main.tf line 7, in resource "vault_aws_auth_backend_config_identity" "example":
│    7:   iam_alias    = "canonical_arn"
