我正在尝试使用TransactWriteItems
更新多个项目,但是出现以下错误:
{
UnknownOperationException: An unknown operation was requested.

}
我的代码如下:
const dynamodb = new aws.DynamoDB({ endpoint: "http://localhost:8000" });
const result = await dynamodb
.transactWriteItems({
TransactItems: [{
"Update":{
"TableName":"dbTable1",
"Key":{
"id": { "S":"table-primary-key-id-01" }
},
"ConditionExpression": "#id = :id",
"UpdateExpression":"set #orderNo = :orderNo",
"ExpressionAttributeNames": {
"#id": "id",
"#orderNo":"orderNo"
},
"ExpressionAttributeValues":{
":id":{"S":"table-primary-key-id-01"},
":orderNo":{"N":"9"}
}
}
}]
})
.promise();
任何帮助都是非常有意义的。提前致谢。

我看到您正在本地dynamodb实例上运行TransactWriteItems操作。不幸的是,AWS尚未实现对dynamodb本地实例的Transactions API调用的支持。
