Cannot convert string to ObjectId in NodeJS

I'm pulling my hair out.

I've tried using mongoose:

const ObjectId = require('mongoose').Types.ObjectId;

let id = new ObjectId(peson["_id"]);

When I console.log(id) it just shows the string value. When I append the id into an array in another object I'm using, and I JSON.stringify() that whole object I get just the '1djd892jowidj3wfejk93' string values.

When I pass my searchObject to Mongo, it doesn't return results.

I've also tried using the native MongoDB driver for node:

const {ObjectId} = require('mongodb');

let id = Objectid("1djd892jowidj3wfejk93")

this also returns just a string value when when logging to the console and also embedding in parent search request. JSON.stringify() shows just the string, and the query returns empty.

the native NodeJs mongoDb driver

The correct way to do this as of December 2023 is as follows

import { ObjectId } from 'mongodb';

const id = ObjectId.createFromHexString(person._id);

If you explore the ObjectId class a bit you can see the other similar methods available. There's a solution in there for sure.

Try this 

var mongoose = require('mongoose');
var id = mongoose.Types.ObjectId('1djd892jowidj3wfejk93');

You don't need to use extra dependency if you are using mongoose,

const mongoose = require('mongoose');

function convertToObjectID(id) {
    return mongoose.Types.ObjectId(id)
}

Try the following:

const {ObjectID} = require('mongodb');
const id = new ObjectID('5e059042b091f6000a4bf236');
