CodeIgniter не возвращает результат 2-й процедуры

Question

1. Я вызываю 2 функции из 2 разных моделей из контроллера покоя.
2. Каждая процедура вызова функции модели.
3. Первая функция модели возвращает результат, а вторая функция модели - нет. возвращает результат. Он возвращает значение $query->num_rows() как 2 строки, но не возвращает $query->result() or $query->result_array() or $query->result_object()
4. После вызова каждой процедуры в функции модели я написал $query->next_result() & $query->free_result()

, но все равно он не работает

Первый контроллер покоя:

public function fetchAll_get() {
    $user = $this->validateToken(); //This
    $results = $this->AdminModel->selectAllAdmin($user);
    $this->set_response($results, REST_Controller::HTTP_OK);
}

Второй контроллер покоя:

public function validateToken() {
        try {
            $token = $this->getBearerToken();
            $payload = JWT::decode($token, SECRETE_KEY, ['HS256']);

            $isUserFound = $this->AuthModel->isUserExists($payload);

            if($isUserFound[0]->Status == "ERROR") {
                $response = array(
                    "Status" => "ERROR",
                    "Message" => "Token is invalid or expired"
                );
                $this->throwError($response);
            } else {
                return $payload;
            }
        } catch (Exception $e) {
            $response = array(
                "Status" => "ERROR",
                "Message" => $e->getMessage()
            );
            $this->throwError($response);
        }
}

Первая модель:

public function isUserExists($user)
{
    $sql = 'call usp_IsUserExists(?, ?)';
    $params = array(
        "username" => $user->userId,
        "userType" => $user->userType
    );
    $query = $this->db->query($sql, $params);
    $result = $query->result();

    $query->next_result();
    $query->free_result();

    return $result;
}

Вторая модель:

public function selectAllAdmin($user)
{
    $results[] = array();

    $sql = 'call usp_SelectAllAdmin(?)';
    $params = array(
        "createId" => $user->userId
    );
    $query = $this->db->query($sql, $params);
    $result = $query->result();

    $results[0]['data'] = $result;

    $query->next_result();
    $query->free_result();

    return $results;
}

Примечание 1: транзакция не требуется для обеих процедур, обе процедуры используются для извлечения данных.

Примечание 2: application/config/database.php

   $db['default'] = array(
                          'dbdriver' => 'mysqli'
                     )

Примечание 3: system/database/drivers/mysqli/mysqli_result.php

function next_result()
{
     if(is_object($this->conn_id))
     {
         return mysqli_next_result($this->conn_id);
     }
}

public function free_result()
{
    if (is_object($this->result_id))
    {
        $this->result_id->free();
        $this->result_id = FALSE;
    }
}
