我正在尝试遵循本教程https://learn.hashicorp.com/tutorials/terraform/gke。我对存储库所做的唯一更改是定义了一个项目名称，该名称等于gcloud config get-value project的结果：
kurtpeek@Kurts-MacBook-Pro ~/g/s/g/k/learn-terraform-provision-gke-cluster (master)> git diff
diff --git a/terraform.tfvars b/terraform.tfvars
index a13174b..4f7eaae 100644
--- a/terraform.tfvars
+++ b/terraform.tfvars
@@ -1,2 +1,2 @@
-project_id = "REPLACE_ME"
+project_id = "kurtpeek-179513"
region = "us-central1"
kurtpeek@Kurts-MacBook-Pro ~/g/s/g/k/learn-terraform-provision-gke-cluster (master)>
gcloud config get-value project
kurtpeek-179513
但是，如果我运行terraform apply，则会收到以以下错误结尾的日志：

根据https://github.com/hashicorp/terraform/issues/20029，这可能是由于不正确的项目名称引起的，但是我相信我已按照指示设置了该变量（https://learn.hashicorp.com/tutorials/terraform/gke#update-your-terraform-tfvars-file）。知道是什么原因造成的吗？ （可从https://github.com/hashicorp/learn-terraform-provision-gke-cluster获得Terraform项目代码）。
