Query Specific Fields of MongoDB from Express.js

Question

I am trying to query a MongoDB for some specific fields from express.js. I have tried several approaches, but without success, including the suggestions found here. I have indeed tried as examples the following (and a few more variations):

 db.collection("Items").find({}, { Name : 1, Price : 1 }, (err, result) => {
  if (result) {
    console.log(result)
  }
 })

Or

 db.collection("Items").aggregate( { $project : { Name : 1, Price : 1 } }, (err, result) => {
  if (result) {
   console.log(result)
  }
})

Here is a working example:

 db.collection("Items").find({}, { projection: { Name : 1, Price : 1 } }).toArray( (err, result) => {
   if (result) {
   console.log(result)
   }
 })
