Are you sure this update call is intended for only one document and not for many documents?

update() is deprecated. I strictly followed the advice in https://mongoosejs.com/docs/deprecations.html to resolve the deprecation warnings and to not change the intended functionality. I used updateOne() because, in this case, update() is only updating the first document found.

Seems like a legit change.
But, don't we need to update mongodb version driver in order to use these new functions?

if(err instanceof Error) return cb(err);
cb(undefined);
});
