Question

对运行时Node.js使用lambda函数6.10
我试图在调用createStack时将客户端提供的令牌（字符串）包含为ClientRequestToken 如果我在传递给createStack函数的参数中包含ClientRequestToken，我会收到以下错误：

    at ParamValidator.fail (/var/runtime/node_modules/aws-sdk/lib/param_validator.js:50:37)

以下是我创建params对象的方法：

var params = {
        StackName: stack_name,
        ClientRequestToken : clientRequestToken,
        Capabilities: [
            'CAPABILITY_IAM'
        ],
        NotificationARNs: [
            'arn:aws:sns:ap-southeast-2:account-id:topic-name'
        ],
        Parameters: parameters,
        Tags: [
            {
                 Key: 'Name',
                Value: 'kktest'
            },
        ],
        TemplateURL: templateUrl
    };

我无法理解这个错误。 ClientRequestToken在createStack方法的文档中明确定义：http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/CloudFormation.html#createStack-property

如果我只是在params对象中注释掉ClientRequestToken，那么createStack调用会成功。所以其余的代码似乎没问题。

我已将此发布到aws论坛，但尚无回复：https://forums.aws.amazon.com/thread.jspa?threadID=257033

有人可以帮忙解决这个问题吗？

lambda环境中当前支持的AWS JS SDK版本似乎是documentation reference的2.45.0。您提到的文档链接的位置有最新版本2.69.0的文档。

我尝试找到＆＃39; ClientRequestToken＆＃39;在latest(2.69.0)，我能够在代码中找到它。当我尝试在version 2.45.0中找到它时，没有＆＃39; ClientRequestToken＆＃39;在代码中。这意味着最近推出了此功能。
