When I put this url {{URL}}api/v1/tours?duration[$gte]=10 into postman console.log(req.query) always returns {duration: {}}

exports.getAllTours = async (req, res) => {
  try {
    const query = Tour.find(req.query);
    console.log(req.query);
    const tours = await query;

    res.status(200).json({
      status: 'success',
      data: { tours },
    });
  } catch (err) {
    res.status(404).json({
      status: 'fail',
      message: err,
    });
  }
};

req.query returns {duration: {}}

I think it has something to do with the schema I am using but I cannot figure out what I need to change
