需要有關 CloudFormation 模板和 AWS lambda 的幫助，以便通過 lambda 將事件從 SQS 拉到 S3

Question

我是 AWS CloudFormation 的新手，我正在嘗試從 SQS 隊列中捕獲事件並通過 AWS lambda 將它們放入 S3 存儲桶中。 事件流是SNS --> SQS <-- Lambda ---> S3 bucket 。

我正在嘗試使用 cloudFormation 模板實現上述流程。部署 CloudFormation 模板后出現以下錯誤消息。 您能提供的任何幫助將不勝感激。 謝謝

代碼拋出錯誤是：

  "AppEventSnsSubscription": {
  "Type": "AWS::SNS::Subscription",
  "Properties": {
    "Protocol": "sqs",
    "Endpoint": {
      "Fn::GetAtt": [
        "AppEventSQSQueue",
        "Arn"
      ]
    },
    "TopicArn": {
      "Ref": "AppEventSNSTopicArn"
    },
    "SubscriptionRoleArn": {
      "Fn::GetAtt": [
        "EventStreamSubscriptionRole",
        "Arn"
      ]
    }
  }
}

我完整的 CloudFormation 模板是：

SubscriptionRoleArn 僅適用於 kinesis：

此屬性僅適用於 Amazon Kinesis Data Firehose交付 stream 訂閱。
