我创建了一个 lambda 函数并将其连接到 AWS API Gateway 以获取我的前端 JSON 格式的 DynamoDB 表数据，我试图从我的 DynamoDB 表中获取我的列条目作为 JSON 格式的列表，但我最终得到了什么getting 是我表中所有条目的完整字符串，它对前端（Flutter）的使用几乎为零。

这是我的 lambda 函数

const AWS = require("aws-sdk");
const documentClient = new AWS.DynamoDB.DocumentClient();

exports.handler = async event => {
  const params = {
    TableName: "//tableName" 
  };
  try {
    // Utilising the scan method to get all items in the table
    const data = await documentClient.scan(params).promise();
    const response = {
      statusCode: 200,
      body: JSON.stringify(data.Items)
    };
    return response;
  } catch (e) {
    return {
      statusCode: 500
    };
  }
};

我的 API 解码后的 JSON 正文

{statusCode: 200, body: [{"product":"clear","__typename":"ProductModel","size":"small","_lastChangedAt":1625829002606,"_version":1,"company":"add","updatedAt":"2021-07-09T11:10:02.578Z","category":"Pot","createdAt":"2021-07-09T11:10:02.578Z","price":"69","description":"this doesn't even make sense","id":"f4acb29c-f8f3-4765-abf6-aef0002a837c"},{"product":"product","__typename":"ProductModel","size":"1","_lastChangedAt":1625988107746,"_version":1,"company":"company","updatedAt":"2021-07-11T07:21:47.704Z","category":"Climbers","createdAt":"2021-07-11T07:21:47.704Z","price":"221","description":"description","id":"0a51d3c3-4df3-4549-abaa-f8b88e8ac407"}]
}

我认为我的 lambda 函数存在问题，因为它的主体部分没有返回列表，但我无法让它工作。任何帮助将不胜感激
