Hi I am getting below error when I try to bind as receiver to receive DLR also no bind is not successful.

I hope someone can fix this bug.

Thank you for your time and support.

PHP 8.2.16

$host = $sending_server->api_link.':'.$sending_server->port;

    \PhpSmpp\Client::$sms_registered_delivery_flag = 0x01;
    \PhpSmpp\Client::$forceIpv4 = true;
    \PhpSmpp\Client::$nullTerminateOctetstrings = false;
    $service = new \PhpSmpp\Service\Listener([$host], $sending_server->username, $sending_server->password, \PhpSmpp\Client::BIND_MODE_RECEIVER, true);
    $service->listen(function (\PhpSmpp\Pdu\Sm $sm) {
        var_dump($sm->msgId);
        if ($sm instanceof \PhpSmpp\Pdu\DeliverReceiptSm) {
            var_dump($sm->state);
            var_dump($sm->state == \PhpSmpp\SMPP::STATE_DELIVERED);
            // do some job with delivery receipt
        } else {
            echo 'not receipt';
        }
    });
