How to remove new ObjectId() from the display of JSON data?

How do I remove the new ObjectId() from my output when displaying JSON data?

Below is my code to get the data using the id from mongodb:

 async get(id) {
    if (!id) throw 'You must provide an id to search for';

    const restaurantsCollection = await restaurants();
    const res = await restaurantsCollection.findOne({ _id: id });
    if (res === null) throw 'No restaurant with that id';

    return res;

The output is:

{
  _id: new ObjectId("6157530bbba1dbb9f7e68e4a"),
  name: 'The Saffron Lounge',
  location: 'New York City, New York',
  phoneNumber: '123-456-7890',
  website: 'http://www.saffronlounge.com',
  priceRange: '$$$$',
  cuisines: [ 'Cuban', 'Italian' ],
  overallRating: 3,
  serviceOptions: { dineIn: true, takeOut: true, delivery: false }
}

The output I want is:

{
  _id: "6157530bbba1dbb9f7e68e4a",
  name: 'The Saffron Lounge',
  location: 'New York City, New York',
  phoneNumber: '123-456-7890',
  website: 'http://www.saffronlounge.com',
  priceRange: '$$$$',
  cuisines: [ 'Cuban', 'Italian' ],
  overallRating: 3,
  serviceOptions: { dineIn: true, takeOut: true, delivery: false }
}

Do I use ObjectId.toString()? Not sure where to use this either

According to this https://docs.mongodb.com/manual/reference/method/ObjectId.toString/ ObjectId.toString() will give you a string that still contains the ObjectId("...") part. You could use a regex to remove that.

async get(id) {
    if (!id) throw 'You must provide an id to search for';

    const restaurantsCollection = await restaurants();
    const res = await restaurantsCollection.findOne({ _id: id });
    
    if (res === null) throw 'No restaurant with that id';
    res._id = res._id.toString().replace(/ObjectId\("(.*)"\)/, "$1")
    return res;
    
 }
