const cloud = require('wx-server-sdk');
cloud.init({ env: cloud.DYNAMIC_CURRENT_ENV });


const db = cloud.database();


exports.main = async (event, context) => {
  const result = await db.collection('goods')
    .skip(0)
    .limit(10)
    .get();
  return {
    dataList: result?.data,
  };
};

   上述代码是官方模板中提供的，但运行报错！错误信息如下：

只要去掉result后面的问号（?）即可成功运行。正确的代码如下：

const cloud = require('wx-server-sdk');
cloud.init({ env: cloud.DYNAMIC_CURRENT_ENV });


const db = cloud.database();


exports.main = async (event, context) => {
  const result = await db.collection('goods')
    .skip(0)
    .limit(10)
    .get();
  return {
    dataList: result.data,
  };
};
