Current Issue Being Resolved:
Screenshot Analysis: You're trying to add PostgreSQL nodes to log service health data but encountering a duplicate key constraint error because you're manually setting id = 0.
Problem: PostgreSQL is rejecting the insert because ID 0 already exists and violates the primary key constraint.

🎯 IMMEDIATE NEXT STEPS (EXACT ACTIONS NEEDED)
CURRENT TASK: Fix PostgreSQL Insert Node
Step 1: Remove ID Field (FIX THE ERROR)
In your PostgreSQL node configuration:
- DELETE the "id" field entirely from "Values to Send"
- OR leave the ID field completely empty (remove the "0")
- Let PostgreSQL auto-increment the ID
Step 2: Correct Configuration Should Be:
Operation: Insert
Schema: public  
Table: service_health_logs
Values to Send:
  - timestamp: {{ $json['timestamp'] }}
  - log_type: {{ $json['log_type'] }}
  - service: api-gateway
  - status: {{ $json['status'] }}
  - message: {{ $json['message'] }}
  - error_details: no_error
  
DO NOT INCLUDE 'id' field - let it auto-increment
Step 3: After Fixing the Insert:

Execute the PostgreSQL node successfully
Verify data insertion: SELECT * FROM service_health_logs;
Add PostgreSQL node to the "Failed Services" branch
Test complete workflow end-to-end
Activate workflow for automatic execution every 5 minutes


🚀 SYSTEM MANAGEMENT (OPERATIONAL COMMANDS)
Quick Start Verification
bash# Navigate to project
cd /Users/yasha/Documents/Tech4biz-Code-Generator/automated-dev-pipeline

# Check all services status
docker compose ps
# Should show all 12 containers as healthy

# Start all services if needed
./scripts/setup/start.sh

# Access interfaces
# n8n: http://localhost:5678 (Pipeline Admin / Admin@12345)
# RabbitMQ: http://localhost:15672 (pipeline_admin / rabbit_secure_2024)
Database Access & Verification
bash# Connect to PostgreSQL
docker exec -it pipeline_postgres psql -U pipeline_admin -d dev_pipeline

# Check table structure
\d service_health_logs

# View existing data
SELECT * FROM service_health_logs ORDER BY timestamp DESC LIMIT 5;

# Exit
