PHP Slim, issue when returning a response

Question

I'm trying to return some content using a Response object. These are the interfaces implemented:

use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Slim\Factory\AppFactory;

Then, in a GET function, i create my own JSON, and trying to reurn it as a response:

$app->get('/getpersons', function(Request $request, Response $response, $args){
    $person= new stdClass();

    $person->id = 1;
    $person->name='Name example';
    $person->address = 'Street example';


    return $response->getBody()->write(json_encode($person));
});

But I'm getting the next error:

Return value of Slim\Handlers\Strategies\RequestResponse::__invoke() must
implement interface Psr\Http\Message\ResponseInterface

I don't have any idea what is happening. Any help?

Solved! Must be written like this:

$response->getBody()->write(json_encode($person));
return $response;
