TypeError: grid.mongo.ObjectID is not a constructor

I've got this JS code for my Next.js API. I'm trying to store images in MongoDB GridFS and retrieve them with a simple API route. The code you are seeing is from a file that gets imported in the API route.

import { MongoClient } from "mongodb"
import Grid from "gridfs-stream"

const { MONGODB_URI, MONGODB_DB } = process.env

if (!MONGODB_URI) {
  throw new Error(
    "Please define the MONGODB_URI environment variable inside .env.local"
  )
}

if (!MONGODB_DB) {
  throw new Error(
    "Please define the MONGODB_DB environment variable inside .env.local"
  )
}

let cached = global.mongo

if (!cached) {
  cached = global.mongo = { conn: null, promise: null }
}

export async function connectToDatabase(dbIndex = 0) {
  if (cached.conn) {
    return cached.conn
  }

  if (!cached.promise) {
    const opts = {
      useNewUrlParser: true,
      useUnifiedTopology: true
    }

    cached.promise = MongoClient.connect(MONGODB_URI, opts).then((client) => {
      const db = client.db(MONGODB_DB.split(",")[dbIndex])
      const grid = Grid(db, MongoClient)
      grid.collection("fs.files")
      return {
        client,
        db: db,
        gfs: grid
      }
    })
  }
  cached.conn = await cached.promise
  return cached.conn
}

When I try to use createReadStream I get the following error:

TypeError: grid.mongo.ObjectID is not a constructor

The issue is with const grid = Grid(db, MongoClient) but I have no idea how to fix it. Any help would be greatly appreciated.

Edit: Fixed the issue. I wasn't meant to use grid.collection.

grid fs stream is depreciated and not needed with newer versions of mongoDB. use GridFSBucket instead.
