代码：
db.collection('news').limit(10).get().then(res=>{colsole.log(res)})
报错信息：
Error: errCode: -502001 database request fail | errMsg: [ResourceUnavailable.ResourceOverdue] Resource has expired. Please renewal fee, but if the problem cannot be solved, contact us.
这段英文拿去翻译一下自己就可以解决了
Resource has expired
基本是欠费了。
到期了，需要续费？
Please renewal fee
