CloudFormation 坚持认为我的 DynamoDB 创建 JSON 无效。但我看不出如何

Question

这是我的对流层生成的JSON (DynamoDB部分):

"sandbox": {
        "Properties": {
            "AttributeDefinitions": [
                {
                    "AttributeName": "audit_id",
                    "AttributeType": "S"
                },
                {
                    "AttributeName": "status",
                    "AttributeType": "S"
                },
                {
                    "AttributeName": "filename",
                    "AttributeType": "S"
                },
                {
                    "AttributeName": "file_detected_dt",
                    "AttributeType": "S"
                },
                {
                    "AttributeName": "time_taken",
                    "AttributeType": "N"
                },
                {
                    "AttributeName": "number_rows_processed_file",
                    "AttributeType": "N"
                },
                {
                    "AttributeName": "number_rows_created_db",
                    "AttributeType": "N"
                },
                {
                    "AttributeName": "info_messages",
                    "AttributeType": "S"
                }
            ],
            "KeySchema": [
                {
                    "AttributeName": "audit_id",
                    "KeyType": "HASH"
                }
            ],
            "ProvisionedThroughput": {
                "ReadCapacityUnits": {
                    "Ref": "ReadCapacityUnits"
                },
                "WriteCapacityUnits": {
                    "Ref": "WriteCapacityUnits"
                }
            }
        },
        "Type": "AWS::DynamoDB::Table"
    }

CloudFormation在尝试启动VPC时给了我这个错误:Property AttributeDefinitions is inconsistent with the KeySchema of the table and the secondary indexes .

但是…是吗?我将audit_id指定为一个单独的键，它肯定存在于AttributeDefinitions列表中。我对CF(和Dynamo，就此事而言)非常陌生，所以我可能会错过一些非常明显的东西，但目前对我来说并不明显。

我搜索了一下，只发现一个提到这个错误，它更多地与开发人员和CF之间的层有关，而不是CF本身。

谁能指出我的模板有什么问题?

这是由于我对DynamoDB的误解。这里应该定义的只有属性将被用作键。因此，将AttributeDefinitions数组更改为以下内容就解决了问题:

"AttributeDefinitions": [
            {
                "AttributeName": "audit_id",
                "AttributeType": "S"
            }
]
