SequelizeDatabaseError

[itsalb3rt]

I have sequelize 6.3.3 and i try used the basic example in repository README and get this error;

{
    "message": "Something goes wrong",
    "data": {
        "name": "SequelizeDatabaseError",
        "parent": {
            "length": 121,
            "name": "error",
            "severity": "ERROR",
            "code": "22P02",
            "position": "167",
            "file": "numutils.c",
            "line": "259",
            "routine": "pg_strtoint32",
            "sql": "SELECT \"id\", \"name\", \"created_at\" AS \"createdAt\", \"updated_at\" AS \"updatedAt\", \"province_id\" AS \"provinceId\" FROM \"cities\" AS \"cities\" WHERE \"cities\".\"province_id\" = '[object Object]' ORDER BY \"cities\".\"id\" DESC LIMIT 10 OFFSET 0;"
        },

Note the "province_id\" = '[object Object]'

When console log to sqs.find(req.query.filter);

{ provinceId: { '$eq': '5' } }

URL: {{HOST}}/api/cities?filter=provinceId eq 5&sort=id desc

The controller:

import City from '../models/City';
import Response from '../utils/response';
import sqs from 'sequelize-querystring';

class CityController {

  static async getAll(req, res) {
    try {
      const { rows, count } = await City.findAndCountAll({
        offset: req.query.offset || 0,
        limit: req.query.limit || 10,
        where: req.query.filter ? sqs.find(req.query.filter) : {},
        order: req.query.sort ? sqs.sort(req.query.sort) : []
      });
      res.json(Response.get('Cities list', rows, 200, { count }));
    } catch (error) {
      res.status(500).json({
        message: 'Something goes wrong',
        data: error
      })
    }
  }
}
