在句柄中使用putObject s3函数时如何解决cffi请求的空调用响应

Question

我正在创建一个计数器，用于计算alexa技能调用CFFI请求的时间。我通过读取和更新处理CFFI的句柄内的s3中的文件来执行此操作。仅CFFI可以正常工作。带有读取文件代码的CFFI可以正常工作。带有写入文件代码的CFFI会写入文件，但返回空调用响应。

我尝试了异步等待承诺。我增加了分配给函数的内存。

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<div class="aux-class green">DIV 1</div>
<div class="aux-class green">DIV 2</div>
<button id="click">Click Me</button>

我希望调用响应中的代码中显示json输出，但是我得到null。

  canHandle(handlerInput) {
    return (handlerInput.requestEnvelope.request.type === 'CanFulfillIntentRequest'
        && (
            handlerInput.requestEnvelope.request.intent.name === 'ProductIntent' ||

  },
  async handle(handlerInput) {

    var s3 = new AWS.S3();
    var params = { Bucket: "toothpaste-counter", Key: "calls.json" };
    var datum;
    var datum2={
      "name": "CFFI5",
      "calls": 5
      };
    ///*JSON.parse(

    await s3.getObject(params, function (err, data) {
      if (!err) 
          datum = JSON.parse(data.Body.toString());
      else
          datum = err;
      //context.succeed();
    }).promise();

    datum.calls++;

    var params2 = { Bucket: "toothpaste-counter", Key: "calls.json", Body: Buffer.from(JSON.stringify(datum)) };

    await s3.putObject(params2, function (err, data) {
      if (!err) 
          datum = JSON.parse(data.Body.toString());
      else
          datum = err;
      //context.succeed();
    }).promise();

    return handlerInput.responseBuilder
      .withCanFulfillIntent(
        {
          "canFulfill": "YES",
          "slots":{
              "voiceExpert": {
                  "canUnderstand": "YES",
                  "canFulfill": "YES"
                }
            }
        })
        .getResponse();
  },
};

我得到的输出 "body": { "version": "1.0", "response": { "canFulfillIntent": { "canFulfill": "YES", "slots": { "voiceExpert": { "canUnderstand": "YES", "canFulfill": "YES" } } } }, "userAgent": "ask-node/2.5.2 Node/v8.10.0", "sessionAttributes": {} } },
