Mongodb was called too many times

Describe the bug
hi, i got this error from mongodb, i searched for it on google https://jira.mongodb.org/browse/NODE-1868 problem because call mongodb too many time.

the options [servers] is not supported
the options [caseTranslate] is not supported
the options [dbName] is not supported
the options [srvHost] is not supported
So I think to create a middleware called end.js. Is this the best way to fix this error ? Thank you

import { mongoClient } from "./database";

export default (req, res, next) => {
mongoClient.close()
console.log("close connect db")
next()
};
