Odoo error when creating a _name_search method for a model (Odoo 14)

In my Odoo app, I have an Area model and a Department model. Every area has a department (Many2One relation). Every department has a code and name. I wanted to overwrite the "_name_search" function in the department so it can be searched using both code and name. But when I am on the Area form view and I start typing in the department_id field for selecting a department on that area, Odoo shows an error

psycopg2.ProgrammingError: operator does not exist: integer = record
LINE 1: ...OM "cusaf_department" WHERE "cusaf_department".id IN ((1, 'A...
                                                             ^
HINT:  No operator matches the given name and argument type(s). You might need to add explicit type casts.

I am working with Odoo 14. Here is my code:

    class Department(models.Model):
        _name = 'cusaf.department'
        _description = 'Departamento'
    
        name = fields.Char(string='Departamento', required=True)
        department_code = fields.Char(string='Código departamento')
        _sql_constraints = [
            ('name_uniq', 'unique (name)',
             "Error: Ya existe un departamento con el mismo nombre"),
            ('name_uniq', 'unique (department_code)',
             "Error: Ya existe un departamento con el mismo código")
        ]
        
        @api.model
        def _name_search(self, name='', args=None, operator='ilike', limit=100):
            if args is None:
                args = []
            domain = args + ['|', ('department_code', operator, name), ('name', operator, name)]
            return super(Department, self).search(domain, limit=limit).name_get()

class Area(models.Model):
    _name = 'cusaf.area'
    _description = 'Area'
    _inherit = ['mail.thread', 'mail.activity.mixin']

    active = fields.Boolean(default=True)

    name = fields.Char(string='Identificador externo', required=True)

    department_id = fields.Many2one('cusaf.department', string='Departamento')

And here is the full error code:

In version 12 the name_search method returns the result of _name_search (list of pairs) as it is without modification but in version 14 it passes the result of _name_search to the browse method and this is where Odoo raises an exception.

To fix the error, you can either return records.ids() or the result of the _search (Query object) method like in many examples in Odoo when they override the _name_search method
