findOne or find on external collection returns 'undefined'

I have 2 applications, one is simple node js app using moongoose and other is meteor js web app. The app with plain node js uses mongoose mode llike so:

var mongoose = require('mongoose')

const testSchema = new mongoose.Schema({


    dummy: {
        type: String,
        required: true,
    },
    id: {
        type: String,
        required: true,
    }
    

});

const Tests = mongoose.model('tests', testSchema);

module.exports =  Tests;

And later i do

var test = new Tests();
test.dummy = "123";
test.save(function(err){
   if(err)
       console.log(err);
});

After that, i go to meteor app, i have a server collection which mapped directly like so:

import { Mongo } from 'meteor/mongo';
import SimpleSchema from 'simpl-schema';

export const Tests = new Mongo.Collection  ('tests');


Tests.schema = new SimpleSchema({
        dummy: {
        type: String,
        required: true,
    },
    id: {
        type: String,
        required: true,
    }

});

Tests.attachSchema(Tests.schema);

i can verify in command line mongo utlity with db.tests.find() there are 2 records in that table. The database name is same in both apps, i checked that. So, i have server method in meteor js like this:

import { Tests } from "../collections/tests";

export const GetDummy  = new ValidatedMethod({
    name: 'GetDummy',
    validate: new SimpleSchema({
        my_id: { type: String  },
    }).validator(),
    run({my_id}) {

        var result = Tests.findOne({id: my_id});
        var test = Tests.findOne();
        test = Tests.find();
        test = Tests.findOne({});
        test = Tests.find({});
        return result;

    },
});

I call this server method from client, set a breakpoint on it and all test variables are undefined! However in the same time i tried to use this collection tests with aldeed:tabular and that plugin is able ot fetch data from that collection somehow. What can be wrong here?
Why does Tests.find() returns undefined, and aldeed:tabluar fetches the data correctly? Why does meteor collection doesn’t map to mongoose created tests?

Your imports are screwed up.
