توجد مشكلة لم افهمها والتي هي ان دالة PATCH ترجع null بدل من تعديل اما دالة DELETE ترجع استجابة خاطئة في next.js

توقيع الدوال في [id]/route.ts غير صحيح قمت بتعريفها كـ PATCH(request, params) وDELETE(request, params) بدلًا من PATCH(request, { params }) وDELETE(request, { params }).

بالتالي params.id يصبح undefined،  عند إنشاء مشروع Next.js (App Router)، فدوال المسارات الديناميكية تستقبل params داخل كائن ثانٍ بشكل هيكلي، والتوقيع الصحيح هو (request, { params }) وليس (request, params)
