ERRO AJAX NO CODEIGNITER

[RafaelScharf 0]

Olá, sou inciante em desenvolvimento e estou trabalhando em um sistema de ponto de venda.

 

Quando faço a busca para vincular o cliente na venda ele da erro na requisição Ajax.

 

Quando faço a busca retorna o seguinte erro no console:

GET http://localhost/aroeira/distribuidora/emporium/customers/suggestions?term=R&limit=10&_=1569833733307 404 (Not Found)

[Deprecation] Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check https://xhr.spec.whatwg.org/.

Veja o código da view/default/pos/add.php

                            }
                            
                        });

                $('#test').click();
                $('select, .select').select2('destroy');
                $('select, .select').select2({minimumResultsForSearch: 7});
            });
            $(document).bind('click', '#test', function () {
                var kb = $('#test').keyboard().getkeyboard();
                kb.close();
                //kb.destroy();
                $('#add-item').focus();
            });

        }

Veja o código do controller Costumer/suggestion

  function suggestions($term = NULL, $limit = NULL)
    {
        // $this->sma->checkPermissions('index');
        if ($this->input->get('term')) {
            $term = $this->input->get('term', TRUE);
        }
        if (strlen($term) < 1) {
            return FALSE;
        }
        $limit = $this->input->get('limit', TRUE);
        $rows['results'] = $this->companies_model->getCustomerSuggestions($term, $limit);
        return $this->sma->send_json($rows);
        
    }

veja agora a model company_model.php

   public function getCustomerSuggestions($term, $limit = 10)
    {
        $this->db->select("id, (CASE WHEN company = '-' THEN name ELSE CONCAT(company, ' (', name, ')') END) as text", FALSE);
        $this->db->where(" (id LIKE '%" . $term . "%' OR name LIKE '%" . $term . "%' OR company LIKE '%" . $term . "%' OR email LIKE '%" . $term . "%' OR phone LIKE '%" . $term . "%') ");
        $q = $this->db->get_where('companies', array('group_name' => 'customer'), $limit);
        if ($q->num_rows() > 0) {
            foreach (($q->result()) as $row) {
                $data[] = $row;
            }

            return $data;
        }
    }

Ja tentei alterar o async: false para async: true e não funcionou.
