Node.js 带Lambda集成的无服务器响应模板

我已经阅读了serverless和AWS的文档，但没有得到响应模板。我有一个lambda函数，它调用另一个模块，该模块将返回一个带有

info

和

error

属性的对象。如果error属性存在，我想抛出一个错误，并用API网关中的响应模板处理它

serverless.yml（不确定

400模式中的内容）

const onboard = async (event) => {
  // returns an object with info/error property
  const response = await someModule();
  /* example response
  const response = {
    error: 'some error',
    name: event.name
  };
  */
  
  if(response.error) {
    context.done(JSON.stringify(response));
  }

  return response;
};

我缺少
statusCodes
属性

  onboard:
    handler: api/onboard.onboard
    events:
      - http:
          path: /onboard
