مرحباً @kjooleng شكراً على الاقتراح!
واجهت مشكلتين: أولاً، طريقتك في إنشاء نص Multipart Body تعمل بشكل جيد للنصوص، لكن الملفات مثل pdf و docx يتم حجبها تماماً بهذه الطريقة.
قمت بتعديلها إلى:

المشكلة الثانية هي أنني عندما أرسل الطلب إلى الخدمة الآن أتلقى:
Content-Type is not supported
لم أبدأ بعد في تصحيح ذلك.
