# Debug Guide: Upload File Android vs iOS ## 📱 Problem - ✅ Upload **IMAGE** berhasil di iOS dan Android - ❌ Upload **PDF** gagal di Android dengan error: `Status: 400 Bad Request` ## 🔍 Root Cause (DITEMUKAN!) ### **Masalah MIME Type PDF** Dari log upload: ``` File details: - Name: 154ce3b0-6fc0-4a39-9e09-3f9aa2b19300.pdf - Type: image/pdf ← ❌ SALAH! - Size: 26534 bytes ``` **Yang benar:** - ❌ `image/pdf` (salah - tidak ada MIME type ini) - ✅ `application/pdf` (benar - standard MIME type untuk PDF) ### **Kenapa Terjadi?** Mobile app (Android) salah set MIME type saat mengirim file PDF. Kemungkinan: 1. File picker/set MIME type salah di mobile code 2. Android WebView auto-detect MIME type incorrectly 3. Mobile app hardcoded MIME type yang salah ## 🛠️ Solusi yang Sudah Diterapkan ### File: `src/app/api/mobile/file/route.ts` **Fix #1: Safe JSON Parsing** - ✅ Cek response sebagai text dulu, lalu parse JSON - ✅ Handle Content-Type yang salah dari external storage **Fix #2: MIME Type Override (LATEST)** - ✅ Deteksi file PDF dari extension (.pdf) - ✅ Override MIME type ke `application/pdf` jika salah - ✅ Rebuild FormData dengan file yang sudah difix **Code:** ```typescript // Jika file PDF tapi type bukan application/pdf, fix it if (fileName.endsWith(".pdf") && originalType !== "application/pdf") { console.log("⚠️ WARNING: PDF file has wrong MIME type:", originalType); console.log("🔧 Overriding to: application/pdf"); // Create new File with correct MIME type const buffer = await file.arrayBuffer(); fixedFile = new File([buffer], file.name, { type: "application/pdf", lastModified: file.lastModified, }); // Rebuild formData with fixed file formData.set("file", fixedFile); } ``` ## 🧪 Cara Testing ### 1. **Test Upload dari Android** Coba upload file PDF dari Android dan perhatikan log di terminal: ```bash # Log yang akan muncul: === UPLOAD REQUEST START === dirId: xxx File details: - Name: dokumen.pdf - Type: application/pdf - Size: 1234567 bytes - Size (KB): 1205.63 =========================== Directory key: xxx === EXTERNAL STORAGE RESPONSE === Status: 400 Status Text: Bad Request Content-Type: text/html; charset=utf-8 ================================= === ERROR: Non-JSON Response === Response text: Unsupported file format... ================================= ``` ### 2. **Informasi yang Perlu Dicari:** Dari log di atas, perhatikan: - **File size** → Berapa MB? (mungkin terlalu besar?) - **File type** → `application/pdf` atau yang lain? - **External storage response** → Status code & message? - **Error text** → Apa yang dikembalikan server external? ### 3. **Compare iOS vs Android** Upload file yang sama dari iOS dan Android, bandingkan log-nya. ## 📊 Expected Log Output ### ✅ Success Case: ``` === UPLOAD REQUEST START === dirId: investment File details: - Name: proposal.pdf - Type: application/pdf - Size: 524288 bytes - Size (KB): 512.00 =========================== Directory key: investment === EXTERNAL STORAGE RESPONSE === Status: 200 Status Text: OK Content-Type: application/json ================================= ✅ Upload SUCCESS ``` ### ❌ Failed Case (Non-JSON Response): ``` === UPLOAD REQUEST START === dirId: investment File details: - Name: proposal.pdf - Type: application/pdf - Size: 5242880 bytes ← Mungkin terlalu besar? - Size (KB): 5120.00 =========================== === EXTERNAL STORAGE RESPONSE === Status: 413 ← Payload Too Large? Content-Type: text/html ================================= === ERROR: Non-JSON Response === Response text: 413 Request Entity Too Large ================================= ``` ## 🔧 Next Steps (Setelah Testing) Berdasarkan log, kita bisa identify masalahnya: ### **Jika masalah FILE SIZE:** - Tambahkan limit validation di frontend - Compress PDF sebelum upload - Increase external storage limit ### **Jika masalah FILE FORMAT:** - Validate file type sebelum upload - Convert format jika perlu - Update external storage allowed formats ### **Jika masalah NETWORK/HEADERS:** - Check user-agent differences - Validate Authorization header - Check CORS settings ## 📝 Checklist Testing - [ ] Test upload PDF kecil (< 1MB) dari Android - [ ] Test upload PDF besar (> 5MB) dari Android - [ ] Test upload PDF dari iOS (baseline) - [ ] Compare log output iOS vs Android - [ ] Check file type yang dikirim - [ ] Check file size yang dikirim - [ ] Check response dari external storage ## 🎯 Goal Dari log yang detail, kita bisa tahu **exact reason** kenapa Android fail, lalu fix dengan tepat. --- **Last Updated:** 2026-04-14 **Status:** ✅ Logging added, ready for testing
