amazon-web-services - 为什么 AWS Cloud Formation 中的堆栈创建会出现错误 : "Provisioned Throughput cannot be left blank"?

Question

AWS Cloud Formation 中的堆栈创建出现此错误:

Provisioned Throughput cannot be left blank

即使我的 JSON 包含该字段？

模板缺少 GlobalSecondaryIndexes 部分的预配置吞吐量参数:

            "GlobalSecondaryIndexes": [
                {
                    "IndexName": "xyz-index",
                    "KeySchema": [
                        {
                            "AttributeName": "xyz",
                            "KeyType": "HASH"
                        }
                    ],
                    "Projection": {
                        "ProjectionType": "ALL"
                    },
                    "ProvisionedThroughput" : {         <== This bit here
                        "ReadCapacityUnits" : "5",
                        "WriteCapacityUnits" : "5"
                    }
                    ...
