Find by _id in mongodb in a node.js

Question

I'm using a node.js and mongodb, and I'm trying get item by _id

  const id = "57bb26e5b2f56d2d47f5e092";
  const tree = db.collection('tree');
  var obj_id = new ObjectID(id);
  const node = tree.findOne({ _id: obj_id });

Result of this query is empty, when i'm trying make that query on mlab.com i get same result, only mongo-shell was return what i expected.

I'm trying that variants:

1. var obj_id = ObjectId(id);

2. var obj_id = "57bb26e5b2f56d2d47f5e092"

Still the same

What i do wrong?

You will need a callback on your findOne method per the documentation here:

http://mongodb.github.io/node-mongodb-native/2.0/api/Collection.html#findOne

If you are using async/await you will need to add the await keyword.
