google-cloud-platform - 为什么我不能在 terraform 中提及子网创建中的 PURPOSE 或角色“此处不需要名为“目的”的参数”

Question

我有一个子网模块，我在 main.tf 中调用它。

resource "google_compute_subnetwork" "vpc_sub_network" {

for_each = var.subnet_info
ip_cidr_range = each.value["subnet_ip_range"]
name = each.value["subnet_name"]
network = each.value["vpc_name"]
region = each.value["region"]
purpose = "INTERNAL_HTTPS_LOAD_BALANCER" --> unable to mention
role = "ACTIVE" --> unable to mention
}

我已经检查了 terraform 的文档，我们可以在创建子网时提及目的和角色

在我的 main.tf

Provider "google"{
creds.....
}
module "vpc_sub_network" {
source = "./modular_approach/modules/general_network/"
}

错误

 on modular_approach\modules\general_network\main.tf line 5, in resource "google_compute_subnetwork" 
 "vpc_sub_network":
        5:   role = "ACTIVE"

 An argument named "role" is not expected here.
