使用地形创建GCP资源时出错

我正试图通过使用地形来创建一个资源。

这是代码

provider "google" {
  project     = "evident-plane-403213"
  credentials = file("evident-plane-403213-1b4230892244.json")
  region      = "us-central1"
  zone        = "us-central1-c"
}

resource "google_compute_instance" "my-instance" {
  name                      = "terraform-instance"
  machine_type              = "f1-micro"
  zone                      = "us-central1"
  allow_stopping_for_update = true

  boot_disk {
    initialize_params {
      image = "debian-cloud/debian-10"
    }
  }

  network_interface {
    network    = google_compute_network.terraform_network.self_link
    subnetwork = google_compute_subnetwork.terraform_subnet.self_link
    access_config {
      // Keeping it empty. It will access over the internet.
    }
  }
}

resource "google_compute_network" "terrform_network" {
  name                    = "terraform-network"
  auto_create_subnetworks = false
}

resource "google_compute_subnetwork" "terraform_subnet" {
  name          = "terraform-subnetwork"
  ip_cidr_range = "10.20.0.0/15"
  region        = "us-central1"
  network       = google_compute_network.terraform_network.id
}

我的资源没有创建,并且出现了一些错误

错误:引用未声明的资源 在主.tf第33行,在资源“google_computer_subnetwork”“terraform_subnet”中: 33:network=google_computer_network.terraform_network.id 托管资源“谷歌计算网络”“地形网络”尚未
在根模块中声明。

错误在哪里?请帮忙解释。
