AWS Lambda测试不从DynamoDB表返回数据

我试图从我的DynamoDB表dashboard获取数据,所以我用表中的一个示例测试Lambda函数。

但我从考试中得到的只是:

  "statusCode": 200,
  "body": "\"Hello from Lambda!\""
}

const AWS = require("aws-sdk");

AWS.config.update({ region: "ap-southeast-1" });

exports.handler = async (event, context) => {
    const ddb = new AWS.DynamoDB({ apiVersion: "2012-10-08" });
    const documentClient = new AWS.DynamoDB.DocumentClient({ region: "ap-southeast-1"});
    
    const params = {
        TableName: "dashboard",
        Key: {
            id: 12345
        }
    };
    try {
        const data = await documentClient.get(params);
        console.log(data);
    } catch (err) {
        console.log(err);
   }
};
