Problem resolving mongodb/monk find() promise

Question

I've run into a problem that simple mongodb/monk find() doesn't work. I know find() returns promise and all 3 ways to resolve it doesn't work. What am I doing wrong? Thanks!

This is my code. All of 3 routes doesn't return at all and need to be canceled:

    const express = require('express');
    const router = express.Router();

    const db = require('monk')('mongodb://127.0.0.1:27017/storage');
    const files = db.get('fs.files');

    router.get('/1', async (req, res) => {
      const result = await files.find();
      res.json(result);
    });

    router.get('/2', (req, res) => {
      files.find()
       .then(
          (result) => { res.json(result) },
          (error) => { res.json(error) }
       );
    });


    router.get('/3', (req, res) => {
      files.find({}, (result) => {
        res.json(result)
      });
    });

    module.exports = router;

UPDATE: I've got rid of munk and native MongoDB driver does the job:

router.get('/', (req, res) => {
  mongo.MongoClient.connect(mongo_uri, mongoClientOptions, async (err, conn) => {
    assert.ifError(err);
    const files = await conn.db('storage')
      .collection('fs.files')
      .find()
      .toArray();
    res.json(files);
  });
});

Problem was I failed to check if munk connection manager returned proper db instance.

Solution: Change db.get('fs.files'); to db.get('files');

This is my demo project -> database: demo, collections: users

const express = require('express');
const app = express();
const db = require('monk')('mongodb://127.0.0.1:27017/demo');
const files = db.get('users');

app.get('/1', async (req, res) => {
  const result = await files.find();
  res.json(result);
});

app.get('/2', (req, res) => {
  files.find()
   .then(
      (result) => { res.json(result) },
      (error) => { res.json(error) }
   );
});

app.get('/3', (req, res) => {
  files.find({}, (result) => {
    res.json(result)
  });
});

app.listen(4000, () => {
    console.log('Example app listening at 4000')
  })
module.exports = app;
