// Fix for multer configuration - replace the problematic section in server.js

// Find this section in server.js (around line 2241):
/*
// Configure multer for file uploads
const storage = multer.diskStorage({
  destination: (req, file, cb) => {
    const userDir = path.join(uploadsDir, req.user?.id || 'anonymous');
    if (!fs.existsSync(userDir)) {
      fs.mkdirSync(userDir, { recursive: true });
    }
    cb(null, userDir);
  },
  filename: (req, file, cb) => {
    // Generate unique filename
    const uniqueSuffix = Date.now() + '-' + Math.round(Math.random() * 1E9);
    const ext = path.extname(file.originalname);
    cb(null, file.fieldname + '-' + uniqueSuffix + ext);
  }
});

// Replace with this corrected version:
const storage = multer.diskStorage({
  destination: (req, file, cb) => {
    const userDir = path.join(uploadsDir, req.user?.id || 'anonymous');
    if (!fs.existsSync(userDir)) {
      fs.mkdirSync(userDir, { recursive: true });
    }
    cb(null, userDir);
  },
  filename: (req, file, cb) => {
    // Generate unique filename
    const uniqueSuffix = Date.now() + '-' + Math.round(Math.random() * 1E9);
    const ext = path.extname(file.originalname);
    cb(null, file.fieldname + '-' + uniqueSuffix + ext);
  }
});
