我试图在AWS上使用无服务器框架部署cube.js项目，当我访问无服务器产生的端点时，在浏览器上导致以下错误

  

无法获取/

这是我的serverless.yml文件

  cubejsProcess:
    handler: cube.process
    timeout: 630
    events:
      - sns: "${self:service.name}-${self:provider.stage}-process"

plugins:
  - serverless-express

我已按照此博客中的步骤进行操作，以设置NAT https://medium.com/@philippholly/aws-lambda-enable-outgoing-internet-access-within-vpc-8dd250e11e12

Cube.js文件如下，其中包含服务器核心选项

const AWSHandlers = require('@cubejs-backend/serverless-aws');
const AthenaDriver = require('@cubejs-backend/athena-driver');

module.exports = new AWSHandlers({
  externalDbType: 'athena',externalDriverFactory: () => new AthenaDriver({
      accessKeyId: process.env.CUBEJS_AWS_KEY,secretaccessKey: process.env.CUBEJS_AWS_SECRET,region: process.env.CUBEJS_AWS_REGION,S3OutputLocation: process.env.CUBEJS_AWS_S3_OUTPUT_LOCATION
  })
});

运行端点

  

https://xxxxx.execute-api.us-east-1.amazonaws.com/production/

由无服务器api网关生成，我得到错误

  

无法获取/

在Cloudwatch上，我看到正在调用cubejs lambda，并查看了有关开始和结束请求ID的日志。我没有在cubejsProcess lambda上看到任何日志。

在哪里/如何调试它以查看问题所在？
