    return $res
       ->withHeader('Content-Type', 'application/json')
       ->getBody()
       ->write(
        json_encode(
            $um->get_all()
        )
    );
});

[AFTER]: Content-Type application/json;charset=utf-8

Working with SOAPUI JSON ;)

$this->get('get_all', function ($req, $res, $args) {
    $um = new UserModel();

    return $res
        ->withHeader('Content-type', 'application/json;charset=utf-8')
        ->withJson($um->get_all());
