Aws lambda SAM AWS Lambda在报告超时问题时工作，但从不返回

我在运行AWS SAM Lambda函数时遇到了一个奇怪的问题，这是我通过AWS SAM API工具发现的。我的lambda请求已完全完成，但函数调用未收到响应

技术：安装了AWS工具包的Windows 10+AWS CLI+AWS SAM+IntelliJ

我从命令行运行SAM

纠正这一问题的努力包括：

• 使用WSL重新安装Windows Docker
• 已清除Docker的所有数据文件夹
• 删除所有docker容器和图像
• 使用Hyper-V在没有WSL的情况下运行Docker
• 完全重新安装后从头开始重新安装AWS CLI和SAM CLI
• 修复AWS CLI和SAM CLI
• 重新启动我的电脑
• 将my template.yaml中的timeuot更新为10秒
• 上述因素的组合

仍然没有回应。该函数是Intellij为node.js 12创建的基本函数。console.log语句可以工作。奇怪的是，在最初的几次尝试中，它似乎可以工作，但没有响应。我尝试使用serverless来匹配NodeJS for CORS中的aws lambda api包示例

My app.js代码：

// const axios = require('axios')
// const url = 'http://checkip.amazonaws.com/';
let response;

exports.lambdaHandler = async (event, context, callback) => {
    console.log('Received event:', JSON.stringify(event, null, 2));
    context.callbackWaitsForEmptyEventLoop = false
    try {
        // const ret = await axios(url);
        response = {
            'statusCode': 200,
            'body': JSON.stringify({
                message: 'hello world',
                // location: ret.data.trim()
            })
        }
    } catch (err) {
        console.log('[Handler] - Main function: ', err);
        return err;
    }
    console.log(response)
    callback(null, response) 
    //return response * also fails with the same output
};

My template.yml：

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: >

    Properties:

      Events:

  HelloWorldApi:
    Description: "API Gateway endpoint URL for Prod stage for Hello World function"
    Value: !Sub "https://${ServerlessRestApi}.execute-api.${AWS::Region}.amazonaws.com/Prod/hello/"
  HelloWorldFunction:
    Description: "Hello World Lambda Function ARN"
    Value: !GetAtt HelloWorldFunction.Arn
  HelloWorldFunctionIamRole:
    Description: "Implicit IAM Role created for Hello World function"
    Value: !GetAtt HelloWorldFunctionRole.Arn

用于启动lambda的命令[使用启动api时发生相同错误]： sam本地启动lambda

Docker正在跑步

然后，该命令用于测试功能：

aws lambda invoke --function-name "HelloWorldFunction" --endpoint-url "http://127.0.0.1:3001" --no-verify-ssl out.txt

有人知道问题是什么吗？我怎样才能解决这个问题？
