Mongoose find() with skip and limit parameters

I am trying to test a collection find with skip and limit parameters

table.test.js

  describe('# GET /api/v1/tables/meta', () => {
    it('should get all tables - meta info only', () =>
      request(app)
        .get('/api/v1/tables/meta')
        .expect(httpStatus.OK)
        .then((res) => {
          expect(res.body).to.be.an('array');
          console.log('res.body:', res.body);
        })
    );
    it('should get some tables w skip limit- meta info only', () =>
      request(app)
        .get('/api/v1/tables/meta?skip=1&limit=10')
        .expect(httpStatus.OK)
        .then((res) => {
          expect(res.body).to.be.an('array');
          console.log('res.body:', res.body);
        })
    );
  });

table.router.js

router.route('/meta')
  /** GET /api/tables - Get list of all tables meta **/
  .get(tableCtrl.listTableMeta);

table.controller.js

function listTableMeta(req, res, next) {
  // const limit = parseInt(req.query.limit, 10);
  // const skip = parseInt(req.query.skip, 10);
  const skip = 1;
  const limit = 10;
  Table.listMeta(req.query, { skip, limit })
    .then(tables => res.json(tables))
    .catch(e => next(e));
}

I have currently 2 tables in the Table collection

First test is OK, I get only one table as expected with hard setting skip/limit in controller

    # GET /api/v1/tables/meta
req params:  {}
skip:  1
limit:  10
Model query:  {}
res.body: [ { _id: '590303660cb7110938272ca2',
    meta: 
     { name: 'TA-PUB-123',
       description: 'TA-Public-123Description',
       owner: '590303640cb7110938272c9b',
       createdAt: '2017-04-28T08:55:02.104Z',
       private: false,
       permissions: [Object] } } ]
      ✓ should get all tables - meta info only

But the second test , with URL params ../tables/meta?skip=1&limit=10 is not giving the same result even with the same hard settings

why these params are modifying the query process ?

thanks for your feedback
