我是Terraform的新手，正在尝试创建一个AWS SNS主题和订阅。我的代码如下所示：

provider "aws" {
  region = "${var.aws_region}"
}

resource "aws_sns_topic" "sns_my_topic" {
  name = "${var.sns_topic_name}"
}

resource "aws_sns_topic_subscription" "code_commit_notification" {
  depends_on  = ["${aws_sns_topic.sns_my_topic}"]

  topic_arn   = "${aws_sns_topic.sns_my_topic.arn}"
  protocol    = "email"    
  endpoint    = "${var.sns_subscribe_endpoint}"
}

但是，运行时出现以下错误输出terraform apply：

Error: aws_sns_topic_subscription.code_commit_notification: resource depends on non-existent resource '${aws_sns_topic.sns_my_topic}'

在添加depends on上面的代码块之前，我也收到了同样的错误（并且在阅读https://github.com/hashicorp/terraform/issues/10462之后，还将其从模块中移出了）。使Terraform处理这些的正确方法是什么？
