CakePHP Virtual Fields send headers?

Question

I have the Users table with the following data:

class User extends Entity
{

protected $_virtual = ['createdformated','modifiedformated'];

protected function _getCreatedformated()
{
    $date = new Time($this->_properties['created']);
    $final=strftime("%d/%m/%Y %H:%M", $date->getTimestamp());
    return $final;
}

protected function _getModifiedformated()
{
    $date = new Time($this->_properties['modified']);
    $final=strftime("%d/%m/%Y %H:%M", $date->getTimestamp());
    return $final;
}
}

If in my controller i call:

    $logusers["data"] = $this->Logusers->find('all')
       ->contain(['Users'])
       ->order(['Logusers.id'=>'DESC']);

     echo json_encode($logusers);

And i get the following after the jsonenconde

 Warning (512): Unable to emit headers. Headers sent in file=C:\wamp\www\otras\mailing\src\Controller\UsersController.php line=91 [CORE\src\Http\ResponseEmitter.php, line 48]

If i leave only 1(ONE) virtual field, the problem is gone... the problem is only when i enable both of them.

What is the problem???

The problem is your echo there.

Do the proper way of sending JSON via CakePHP or pass the json to the response body and return the response in your controller action.
