If the current behavior is a bug, please provide the steps to reproduce.

import/require mongoose

Welcome to Node.js v14.0.0.
Type ".help" for more information.
> const m = require('mongoose');

What is the expected behavior?

no errors

What are the versions of Node.js, Mongoose and MongoDB you are using? Note that "latest" is not a version.

node 14.0.0
mongoose 5.9.

[AbdelrahmanHafez]

I can confirm that running this on Node 14 triggers those warnings.

[greyliances]

Exact same issue, it seems to work fine but just "spams" the console with it on startup

Nodejs 14.0.0 and mongoose 5.9.10

[AbdelrahmanHafez]

Apparently that's an issue with the native driver, I opened up an issue on jira, let's follow the progress there.

Will keep this issue open as a reference until mongodb v3.5.7.

Apparently, it has been fixed: https://github.com/mongodb/node-mongodb-native/commit/56a1b8aec3c4855b2709b27ff3127018cc2577aa

[malinhanak]

I read about the driver issue on Jira but I still get this error, I don't have mongodb installed, connected via app url instead so Im only running mongoose with node 14. Do I need to update anything?

[AbdelrahmanHafez]

@malinhanak This is from the native mongodb driver, which is used by mongoose, not the database itself. There's a PR with upgrading mongodb which will fix the warning, should be fixed on [email protected]
