const query = { uuid: '12212121212112' };
const values = { $set: {name:'av'} };
const result = await databaseConnection.collection('person');
let data = await result.findOneAndUpdate(query, values, { new: true });
console.log(data) //old document getting printed

This is my code. In here I am using {new: true} but somehow still its returning the old document instead of the updated one.

Configuration is-

 "mongodb": "^3.5.7",
 "mongoose": "^5.9.17",

node version- v14.17.3

What is wrong with this?

P.S.- In another project with the same configuration it's working fine.

mongoose mongodb

try this way...

let result = await db1.updateOne({ _id: 'XXXXXXXXX' }, { $set: { name: 'My name' } }, { returnNewDocument: true });
    console.log(result.data.value) //new document getting printed

Replace line no.4 with below:

let data = await result.findOneAndUpdate(query, values, { returnOriginal: false, returnDocument: "after" });

Works for me ! Thanks
