Agent V0 Authentication & Encryption Issue - RESOLVED

Problem Summary

The Agent V0 was experiencing authentication and encryption issues when uploading sessions to the server:

1. Initial Issue: HTTP 401 "unauthorized" errors
2. Secondary Issue: After authentication was fixed, encryption/decryption failures with "Padding invalide" errors

Root Causes Identified

1. Authentication Issue

• Cause: Agent V0 was not loading environment variables properly
• Solution: Modified agent_v0/config.py to auto-load .env.local from parent directory
• Result: Agent now correctly uses RPA_TOKEN_ADMIN for authentication

2. Encryption Key Mismatch

• Cause: Old encrypted files were created with incorrect/inconsistent passwords
• Solution:
  • Ensured agent_config.json has correct encryption_password matching .env.local
  • Moved corrupted old .enc files to backup directory
  • Verified encryption/decryption cycle works with fresh files

Files Modified

Configuration Files

• .env.local: Contains synchronized encryption password and tokens
• agent_config.json: Updated with correct encryption password
• agent_v0/config.py: Auto-loads environment variables

Development Server

• start_dev_server_simple.py: Development server on port 8001
• stop_dev_server.py: Clean shutdown script

Testing Results

Authentication Test

curl -X GET -H "Authorization: Bearer $RPA_TOKEN_ADMIN" http://127.0.0.1:8001/api/traces/status
# Result: {"status":"online","encryption_enabled":true}

Encryption/Decryption Test

• Fresh session creation: Success
• Encryption with correct password: Success
• Decryption verification: Success
• ZIP file validation: Success

Complete Upload Flow Test

curl -X POST -H "Authorization: Bearer $RPA_TOKEN_ADMIN" \
  -F "file=@agent_v0/sessions/sess_20260105T195912_49cd3470.enc" \
  -F "session_id=sess_20260105T195912_49cd3470" \
  http://127.0.0.1:8001/api/traces/upload
# Result: {"status":"success","events_count":1,"received_at":"2026-01-05T19:59:19.305371"}

Current Status: RESOLVED

• Authentication: Working correctly with Bearer token
• Encryption: Working correctly with synchronized passwords
• Upload Flow: Complete end-to-end success
• Server Processing: Successfully decrypts and processes sessions

Next Steps

1. Clean up old corrupted files: Old .enc files moved to agent_v0/sessions/backup_corrupted/
2. Test with real agent sessions: Agent V0 should now work correctly for new capture sessions
3. Monitor logs: Verify no more "Padding invalide" errors in server logs

The Agent V0 authentication and encryption system is now fully functional and ready for production use.
