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:

File picker/set MIME type salah di mobile code
Android WebView auto-detect MIME type incorrectly
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:

// 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:

# 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: <html><body>413 Request Entity Too Large</body></html>
=================================

🔧 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.
