{
  "activeSystems": [
    {
      "id": "octant",
      "name": "Octant",
      "enabled": true,  // Set to false to disable

🔒 Security & Configuration

Systems Management Security

⚠️ Important Security Note: System enable/disable operations can only be performed by manually editing the configuration file. No API endpoints allow modifying system status for security reasons.

To Enable/Disable a System:

1. Edit Configuration File: Modify server/config/systemsConfig.ts
2. Change enabled flag: Set "enabled": true/false for the target system
3. Restart Application: The server must be restarted for changes to take effect

Configuration Structure:

{
  "activeSystems": [
    {
      "id": "system-identifier",
      "name": "System Name",
      "displayName": "Public Display Name",
      "source": "opengrants" | "daoip5" | "custom",
      "enabled": true,  // Manual control only
      "priority": 1,    // Display order
      "metadata": {
        "description": "System description",
        "website": "https://system-website.com",
        // ... additional metadata
      }
    }
  ]
}

API Access:

• Public Endpoints: Only return information about enabled systems
• Configuration Viewing: Read-only access to active systems configuration
• No Modification API: No endpoints exist for changing system status

🚨 Troubleshooting

Common Issues

1. Database Connection Error

Error: DATABASE_URL must be set

Solution: Ensure valid DATABASE_URL in .env file

2. Systems Configuration Error

Failed to load systems configuration: ENOENT

Solution: Ensure server/config/systemsConfig.ts exists and is properly formatted

3. Port Already in Use

Error: listen EADDRINUSE: address already in use :::5000

Solution: Change port in .env or kill existing process:

# Change port
echo "PORT=3000" >> .env

# Or kill process
lsof -ti:5000 | xargs kill -9

4. pnpm Not Found

# Install pnpm globally
npm install -g pnpm

# Or use npm instead
npm install
npm run dev

5. TypeScript Errors

# Check for type errors
pnpm run check

# Clean install if needed
pnpm run install:clean

6. Database Schema Issues

# Reset database schema
pnpm run db:push

7. System Not Appearing in Dashboard

1. Check systemsConfig.ts - ensure "enabled": true
2. Restart the development server
3. Verify system configuration syntax is correct
