Men Express yordamida NodeJS backend yaratyapman va quyidagi xatoliklarni ko'ryapman: `Uncaught TypeError: Cannot read properties of undefined (reading 'id')` Mening bu xatolik sodir bo'lgan kodim quyidagicha: ``` app.delete'/post', (req, res) => { const user = getUser(req.user.user_id); if (!user) return res.sendStatus(401); post = getPostreq.body.id); if (!post) return res.sendStatus(404); if (post.user_id!=q.re.user_id) return res.sendStatus(403); // Kod, qaytarib berish orqali postni o'chirib tashlaydi DB res.Status res.send); }(201);<|eot_id|><|start_header_id|>assistant<|end_header_id|>

"Uncaught TypeError: Cannot read properties of undefined (reading 'id') " xatosi "req.body.id" aniqlanmaganligi sababli yuzaga kelishi mumkin. Ushbu xatolikni hal qilish uchun siz uning xususiyatlariga kirishdan oldin "req.body.id" mavjudligini tekshirish uchun tekshiruv qo'shishingiz kerak. Buni "req.body.id" ga kirishdan oldin shartli buyruq qo'shish orqali amalga oshirishingiz mumkin: '' app.delete'/post', (req, res) => {user = getUserreq.user_id); if (!req.body.id) returnuser.resendStatus{401}; if (!req.body.id) returnuser.resendStatus{400}; post get{(post}req.body.id); if (post!re<|eot_id|><|start_header_id|>user<|end_header_id|>
