如何从 mongodb 返回引用数组？

Question

I've got json like below, stored in mongodb:

{
  createdAt: 1641840199,
  name: 'hello'
  projects: [ new ObjectId("61dc99b2fdfbd72f33d4d699") ]
}

in projects array i've got an reference to the documents with project. And now i've got a question, how to return an array of this objects (full objects, not only it reference id).

PS. I'm using mongodb library, i do not like moongose .

Thanks for any help!

You can try this code:

db.NAME.findOne({ projects: ObjectId("61dc99b2fdfbd72f33d4d699") });
