Onboarding, renewal and revocation

السلام عليكم
حصلت على CSID المبدئي للامتثال
وارسلت عدد من الفواتير الضريبية القياسية والاشعارات دائن/مدين بنجاح واريد الان تسجيل production CSID
حيث استخدم لغة php

$authValue = base64_encode($api['csid'] . ':' . $api['secret']);
$headers = [
    "Authorization: Basic $authValue",
    "Accept: application/json",
    "accept-version: v2",
    "Accept-Language: en",
    "Content-Type: application/json",
];

    $payload = json_encode(['compliance_request_id' => (string)$api['last_request_id']], JSON_UNESCAPED_SLASHES);

    $ch = curl_init($url);
    curl_setopt_array($ch, [
        CURLOPT_POST           => true,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_HTTPHEADER     => $headers,
        CURLOPT_POSTFIELDS     => $payload,
        CURLOPT_SSL_VERIFYPEER => true,
        CURLOPT_SSL_VERIFYHOST => 2,
        CURLOPT_TIMEOUT        => 30, 
    ]);

حيث ان بيانات الارسال :

ورغم ذلك تظهر لي رسالة الخطأ التالية
