single sign on - exception happen on the callback of sso in moodle

Question

I am trying to implement SSO in moodle, and it works but on the callback after the user login I got the following exception

Here is the code that found in the mentioned file

require_once(__DIR__ . '/../../../config.php');
require('../setup.php');

// First setup the PATH_INFO because that's how SSP rolls.
$_SERVER['PATH_INFO'] = '/' . $saml2auth->spname;

try {
    require($CFG->dirroot.'/auth/saml2/extlib/simplesamlphp/modules/saml/www/sp/saml2-acs.php');
} catch (Exception $e) {
    throw new saml2_exception($e->getMessage(), $e->getTraceAsString());
}
