facebook - Getting `Unsupported get request` error only on certain ID -

i'll start example, easier understand. have script:

facebooksession::setdefaultapplication('536443039714362', '007d98b0f51f3ffecb206987fc3bc624'); $session = new facebooksession('access-token'); $session = facebooksession::newappsession(); $event = (new facebookrequest( $session, 'get', '/loftasvilnius'))->execute()->getgraphobject(graphuser::classname())->asarray();

as see gets info of page prefix 'loftasvilnius'. , works fine here.

could explain that's wrong here ?
