云函数本地调试换成最简单的查询还是一直出错，CloudSDKError？

const cloud = require('wx-server-sdk')

cloud.init();

// 云函数入口函数

exports.main = async (event, context) => {

const wxContext = cloud.getWXContext();

//console.log(cloud);

const db = cloud.database()

const recruit= await db.collection('recruit_school').limit(10).get();

console.log(recruit);

return {

event

}

}
