Account Creation Issue Analysis

Problem Summary

User is trying to add a LinkedIn account but despite successful API calls (200 responses), the account doesn't appear in the database.

Log Analysis

Successful Operations Observed:

1. GET /api/accounts - Multiple successful requests returning 200
2. Supabase API calls - Successful queries to Social_network table
3. POST /api/accounts - Successful request returning 200
4. Auth callback - Successful OAuth callback with authorization code

Key Issues Identified:

1. Missing database insertion - No logs showing successful account creation in database
2. OAuth callback flow - The callback handler may be failing silently
3. Data persistence - Accounts are being retrieved but not stored properly

Root Cause Analysis

1. OAuth Callback Flow Issue

The logs show a successful auth callback:

GET /auth/callback?code=AQQe_UpcxzZsgqMcsO-CnPi07wyc-Uh6cv6WVwPbFWm-4MsQ-OvJCmDuyOWlvK5e_67rrpZjiunqWHLd8rv5uvDJg_T2pPhvDj6BJYzmpDF_RpktHJQnOqQEiEsuaG8ZImd_wFsRI9-6T5A3-9wYuZVQhtkwdIDsZ4Dofp54_jbyzCLUrahbzfkRlL2c29DeWvfP9jTy8bQF1AeYLEA&state=KUXEkZ7fZjsrZWxJxm4E-do2UysOvF45Kipvk00kfUM

But there's no corresponding log entry for the /accounts/callback POST request that should follow.

2. Database Insertion Problem

The OAuth callback handler in backend/api/accounts.py:169-183 should insert data into the Social_network table, but there's no evidence this is happening.

3. Error Handling Issues

The error handling in the OAuth callback may be swallowing exceptions and returning 200 even when failures occur.

Diagnostic Plan

Phase 1: Immediate Debugging

1. Add detailed logging to track the complete OAuth flow
2. Verify database schema and table structure
3. Test database permissions and insert operations
4. Check user ID mapping between auth and database

Phase 2: Flow Verification

1. Test the complete OAuth flow end-to-end
2. Verify data insertion at each step
3. Check for data validation issues
4. Test error scenarios and edge cases

Phase 3: Database Investigation

1. Check existing records in Social_network table
2. Verify table constraints and indexes
3. Test manual insertion to isolate the issue
4. Check for triggers or RLS policies

Technical Architecture

Account Creation Flow:

Frontend → POST /api/accounts → Initiate OAuth → Redirect to LinkedIn
LinkedIn Callback → GET /auth/callback → Frontend handles callback
Frontend → POST /accounts/callback → Backend processes OAuth code
Backend → Insert into Supabase Social_network table → Return success

Key Components:

• Frontend: LinkedInCallbackHandler.jsx
• Backend: accounts.py - OAuth callback handler
• Database: Supabase Social_network table
• Service: LinkedInService

Recommended Actions

Immediate Actions:

1. Add debug logging to the OAuth callback handler
2. Verify the callback endpoint is being called
3. Check database connection and permissions
4. Test manual insertion to isolate the issue

Long-term Fixes:

1. Improve error handling to provide detailed feedback
2. Add database validation and constraints
3. Implement proper logging for all operations
4. Add monitoring for account creation success/failure rates

Next Steps

1. Create a debug script to test the database connection and table structure
2. Add detailed logging to track the OAuth callback flow
3. Verify the callback endpoint is receiving the correct data
4. Test the database insertion process with sample data
5. Check for any RLS policies or triggers that might block insertion
