🔧 API Format Fix:
- Convert register.ts to register.js using req/res pattern
- Convert login.ts to login.js using req/res pattern
- Convert setup-auth.ts to setup-auth.js using req/res pattern
- Use CommonJS require() instead of ES6 imports
- Use traditional Vercel function signature that works
✅ Working Format:
- export default async function handler(req, res)
- req.body for request data (auto-parsed by Vercel)
- res.status().json() for responses
- CommonJS modules with require()
This should resolve all timeout issues and make authentication work properly.
🔧 Debugging Improvements:
- Optimize setup-auth endpoint to avoid timeouts
- Add table existence checks before operations
- Simplify permission system for faster setup
- Add environment variable validation
- Create test-db endpoint for connection debugging
🚀 Performance Optimizations:
- Break down large SQL queries into smaller chunks
- Add early returns for already-setup scenarios
- Reduce permission complexity during initial setup
- Better error messages for troubleshooting
🧪 New Debug Endpoints:
- /api/test-db - Test database connectivity
- /api/setup-auth - Optimized schema setup
These changes should resolve timeout issues and provide better debugging information for authentication problems.
🐛 Bug Fix:
- Replace req.json() with req.text() + JSON.parse() for Vercel compatibility
- Add proper error handling for malformed JSON requests
- Fix authentication endpoints (login/register) body parsing
- Fix admin users endpoint body parsing
🔧 Technical Details:
- Vercel functions don't support req.json() method directly
- Use req.text() to get raw body content then parse manually
- Add try/catch blocks for JSON parsing errors
- Maintain same API interface and error responses
✅ Endpoints Fixed:
- /api/auth/register - User registration
- /api/auth/login - User authentication
- /api/admin/users - Admin user management
This resolves the 'req.json is not a function' error in production.
