Amazon dynamodb 在Alexa技能上更新项目DynamoDB表时出现问题

我试图更新表中的一个项目，该技能只有一个目的，它应该根据条件将项目“状态”更新为“开”或“关”

const Alexa = require('ask-sdk');
var AWS = require("aws-sdk");

AWS.config.update({region: "ap-southeast-2"});

    },
    handle(handlerInput) {
        const speakOutput = 'Welcome';
        return handlerInput.responseBuilder
            .speak(speakOutput)
            .reprompt(speakOutput)
            .getResponse();
    }
};


const LivingRoomLightsIntentHandler = {
    canHandle(handlerInput) {
        return Alexa.getRequestType(handlerInput.requestEnvelope) === 'IntentRequest'
            && Alexa.getIntentName(handlerInput.requestEnvelope) === 'LivingRoomLightsIntent';

        const deviceID = "livingRoomLights"

        if (LightStatus === "On") {

            const status = "true"

// The intent reflector is used for interaction model testing and debugging.

这是日志

请帮忙

DynamoDb使用2个唯一ID来检测特定行。

---

确保您发送的信息正确无误。然后只检测您的行并更新值。

请排除所有不相关的代码。例如，这是alexa问题还是dynamodb问题？您可以通过运行代码来解决这个问题，而无需从alexa触发。如果您可以将代码示例缩减为导致问题的几行代码，您将得到更好的答案，请参见：请向我们展示lambda函数的文件结构！我希望这是因为lambdat中的文件夹结构不正确。文件结构是在开发人员控制台中创建托管Alexa skill时默认创建的原始结构。
