Problems with filter in lib API QUERY PARAMS

I'm using this lib to apply filters

api-query-params

I need to filter for this entity;

'use strict'

const mongoose = require('mongoose');
const Schema = mongoose.Schema;


const schema = new Schema({
    id: {
        type: String,
        trim: true
    },
    name: {
        type: String,
        trim: true

    },
    description: {
        type: String,
        trim: true
    },
    restaurantId: {
        type: String,
        trim: true
    },
    price: {
        type: Number,
        trim: true
    },

})

module.exports = mongoose.model('Menu', schema);

Through the API documentation QUERY PARAMS can create this method;

exports.list_all_dataProviders = async (req, res) => {
     const { filter, skip, limit, sort, projection } = aqp(req.query);

    Menus
      .find(filter)
      .skip(skip)
      .limit(limit)
      .sort(sort)
      .select(projection)
      .exec(async (err, result) => {

        if (err) {
          return res.status(500).jsonp({message:"There was an internal error listing all the providers " + err});
        }
        let count = await Menus.find().count()
        res.status(200).jsonp({
          size: limit,
          page: skip,
          total: count,
          data: result
        });
      });
  };

And I did the following tests on Postman;

http://localhost:3000/menu?price=14.9

http://localhost:3000/menu?price=4.9

http://localhost:3000/menu?price=6.9

And it took perfectly, but I did this test and I did not succeed;

It could not perform any filter for the description field http://localhost:3000/menu?description=Coberto

And for the field name only managed to get the first record.

What's wrong is my method, I need to fix it.
