AttributeError: объект «bool» не имеет атрибута «pop» — сообщество Odoo v8 — Odoo v10

У меня есть этот метод, который представляет собой кнопку:

@api.multi
def search_partner_seniat(self):
    """ Check vat of the partner and update iva rate
    """
    self.ensure_one()
    vat = self.vat.upper()
    res = {
        'name': _('The requested contributor does not exist'),
        'vat_subjected': False,
        'vat': vat,
        'wh_iva_agent': False,
        'wh_iva_rate': 0.0
    }

    if 'VE' in vat:
        vat = vat[2:]

    # assumption: both methods in new api style
    if self.env['res.partner'].check_vat_ve(vat): 
        res = self.env['seniat.url']._dom_giver(vat)  
    self.write(res)

    return {
        'type': 'ir.actions.act_window',
        'res_model': 'search.info.partner.seniat',
        'view_mode': 'form',
        'view_type': 'form',
        'res_id': self.id,
        'views': [(False, 'form')],
        'target': 'new',
    }

Он должен возвращать NIF res.partner, но каждый раз, когда я нажимаю на него, он выдает мне это:

Ошибка приходит сюда:

    if self.env['res.partner'].check_vat_ve(vat): 
        res = self.env['seniat.url']._dom_giver(vat) 
    self.write(res)

Я не знаю, могут ли быть причиной эти две модели, они отлично работают, насколько я помню, на партнере:

@api.model
def check_vat_ve(self, vat): #, context=None
    """ Check Venezuelan VAT number, locally called RIF.
    RIF: JXXXXXXXXX RIF VENEZOLAN
         IDENTIFICATION CARD: VXXXXXXXXX
         FOREIGN IDENTIFICATION CARD: EXXXXXXXXX
    """

    #if context is None:
        #context = {}
    if re.search(r'^[VJEGP][0-9]{9}$', vat):
        return True
    if re.search(r'^([VE][0-9]{1,8}|[D][0-9]{9})$', vat):
        return True
    return False

On seniat_url:

@api.multi
def _dom_giver(self, vat): 
    """ Check and validates that the vat is a passport,
    id or rif, to send information to SENIAT and returns the
    partner info that provides.
    """
    #if context is None:
        #context = {}
    name = ''
    url_seniat = ''

    url_obj = self.search([], limit=1) #self.browse(self.search([]))#[0] #(cr, uid, self.search(cr, uid, []))[0]
    #url1 = url_obj.name + '%s' %(value or '')
    #url2 = url_obj.url_seniat + '%s' %(value or '')
    if url_obj.name:
        name = url_obj.name

    if url_obj.url_seniat:
        url_seniat = url_obj.url_seniat
    url1 = name + '%s'
    url2 = url_seniat + '%s'
    vat = self._validate_rif(vat) #cr, uid, vat, context=None
    if vat:
        return self._get_rif(vat, url1, url2) #cr, uid, vat, url1, url2, context=context
    else:
        return False

Любые идеи?
