🎉 COMPLETE SUCCESS - OpenHands n8n Integration

Date: 2025-11-30 Status: ✅ BREAKTHROUGH ACHIEVED - PRODUCTION READY

🏆 MISSION ACCOMPLISHED

After 13+ hours of comprehensive testing across multiple approaches, we have successfully achieved OpenHands integration with n8n using the SDK approach, completely bypassing all Docker networking issues that blocked CLI, API, and headless methods.

📈 JOURNEY SUMMARY

Failed Approaches (12 hours):

CLI Approach - TTY requirements blocked
API Approach - Docker runtime timeout
Headless Mode (v0.62) - Same networking issue
Headless Mode (v0.61) - Confirmed same blocker

Successful Approach (1 hour):

SDK Approach - ✅ COMPLETE SUCCESS

Timeline: Total investment 13+ hours, with breakthrough in final hour

🚀 FINAL SOLUTION: OpenHands SDK

✅ What's Working:

Native Python execution - No Docker required
Built-in tool system - FileEditor, Terminal, TaskTracker
Direct LLM integration - MiniMax API compatible
Perfect n8n integration - Simple SSH node execution
Production-ready wrapper - /home/bam/openhands-sdk-wrapper.py

✅ Architecture:

Gitea Push → n8n Webhook → SSH Node → Python SDK → File Creation
