Question

我有以下代码，我尝试部署到CloudFormation。出于某种原因，它坚持认为我错过了模板中的关键元素。

因为我在资源S3NotificationBucketPolicy中修改了存储桶策略，所以我才开始收到此错误。

任何见解都会很棒。

    }
  }
}

即使我已经说明了所需的元素，它也会失败并显示以下消息。

您的问题是S3NotificationBucketPolicy政策文件有额外的Version和Statement：

"S3NotificationBucketPolicy": {
    "Type": "AWS::S3::BucketPolicy",
    "Properties": {
        "Bucket": {
            "Ref": "S3NotificationBucket"
        },
        "PolicyDocument": {
            "Version": "2012-10-17",      <-- Here
            "Statement": [{
                "Version": "2012-10-17",  <-- And here
                "Statement": [{
                    "Sid": "AWSCloudTrailAclCheck20150318",

删除其中一个（以及匹配的右括号），你就可以了。
