$file->getSize() and $file->getRealType() not working

Hello, I've found the following error, and looking for a solution I found this code on github for someone who is just like me. https://github.com/phalcon/cphalcon/issues/1931

Code:

foreach ($this->request->getUploadedFiles() as $file) {
var_dump($file, $file->getName(), $file->getTempName(), $file->getType(), $file->getSize(), $file->getRealType());
}

Results:

object(Phalcon\Http\Request\File)#82 (6) {

string(11) "suspect.gif"
["_tmp":protected]=>
string(14) "/tmp/phpUNwfs6"
