为什么 AWS 云形成中的堆栈创建出现错误："Provisioned Throughput cannot be left blank"？

Question

AWS Cloud Formation 中的堆栈创建给出此错误：

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"
                    }
                    ...

模板

看起来不错，但是在My_tabls"之前有一个奇怪的字符，应该是"，而不是"

"TableName": “My_Table",

类似的奇怪角色也“ GlobalSecondaryIndexes的一部分。
