Implementation Details

Enhanced Logging Features

  • OAuth Flow Tracking: Complete visibility into OAuth callback processing
  • Database Operations: Detailed logging of all database interactions
  • Error Detection: Specific error messages and stack traces
  • Performance Monitoring: Timing and response size logging

Testing Infrastructure

  • Automated Testing: Scripts to verify database and OAuth functionality

  • Troubleshooting: Comprehensive troubleshooting checklist

How to Use the Enhanced System

Running Tests 

# Test database connection
cd backend
python test_database_connection.py

# Test OAuth flow
python test_oauth_flow.py

Enhanced Logging

The enhanced logging will now provide detailed information:

  • Backend: Look for 🔗 [OAuth], 📱 [Accounts], ➕ [Accounts] prefixes
  • Frontend: Look for 🔗 [Frontend] and 🔗 [LinkedIn] prefixes in console

Monitoring Account Creation

  1. Start Backend: python app.py
  2. Start Frontend: npm run dev
  3. Add Account: Try to add a LinkedIn account
  4. Check Logs: Monitor for enhanced logging messages

Expected Results

Successful Account Creation

With the enhanced logging, you should now see:

  1. OAuth Initiation: ➕ [Accounts] Add account request for user: <user_id>
  2. OAuth Callback: 🔗 [OAuth] Starting callback for user: <user_id>
  3. Token Exchange: 🔗 [OAuth] Token exchange successful
  4. User Info: 🔗 [OAuth] User info fetched: <user_info>
  5. Database Insertion: 🔗 [OAuth] Database response: <response>
  6. Success Confirmation: 🔗 [OAuth] Account linked successfully

Error Detection

If there are issues, you'll see specific error messages:

  • Database connection errors
  • OAuth configuration issues
  • Token exchange failures
  • Database insertion problems
