CloudFormation 坚持我的 DynamoDB 创建 JSON 无效..但我看不出如何

CloudFormation insists my DynamoDB creation JSON is invalid .. but I can't see how

这是我的对流层生成的(DynamoDB 部分)JSON:

"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。我是 CF(和 Dynamo,就此而言)的新手,所以我可能会遗漏一些非常明显的东西,但目前对我来说并不明显。

我用谷歌搜索了一下,只发现了一个提到这个错误的地方,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?

这是我对 DynamoDB 的误解。应在此处定义的 only 属性将用作键。因此,将 AttributeDefinitions 数组更改为以下内容解决了问题:

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