#49 feat: supabase edge functions error handling

Update our all supabase edge functions. When errors happens, call this n8n webhook url with POST:

https://smartbotics.app.n8n.cloud/webhook/235904a4-7810-4bdb-a2b2-c35b7f9411e3

Where the body contains unified and detailed error information formatted in json.

Authentication required (JWT Auth) where the secret is: cica

@fszontagh I'm starting work on this issue now!

I'll implement centralized error handling across all Supabase Edge Functions that:

1. Creates a shared error handler utility that sends errors to the n8n webhook
2. Uses JWT authentication with the provided secret
3. Formats error information in a unified JSON structure
4. Updates all existing Edge Functions to use this centralized error handler

I'll begin by:

• Creating a shared error handling utility in _shared/
• Identifying all existing Edge Functions
• Updating each function to integrate the error handler
• Testing the implementation

Starting implementation now...

Progress Update

I've successfully created the centralized error handler and updated the following Edge Functions:

✅ Completed:

1. _shared/error-handler.ts - Centralized error handling utility created
2. api - Updated with error handler
3. auth - Updated with error handler
4. oauth-shopify - Updated with error handler
5. oauth-woocommerce - Updated with error handler
6. oauth-shoprenter-init - Updated with error handler

🔄 In Progress:

Currently updating the remaining ~12 Edge Functions:

• oauth-shoprenter-callback
• webhooks-shopify
• webhook-shoprenter-uninstall
• trigger-sync
• shopify-sync, woocommerce-sync, shoprenter-sync
• shoprenter-scheduled-sync, woocommerce-scheduled-sync
• shoprenter-products, shoprenter-orders, shoprenter-customers
• get-ai-context

The error handler provides:

• Unified error formatting in JSON
• Automatic error reporting to n8n webhook with JWT authentication
• User context extraction from requests
• Non-blocking webhook calls (won't affect function performance)
• Wrapper function for easy integration

Continuing with the remaining functions...

✅ Implementation Complete

I've successfully implemented centralized error handling across all Supabase Edge Functions!

What Was Done

1. Created Centralized Error Handler (_shared/error-handler.ts)

• Unified error formatting in JSON with consistent structure
• Automatic error reporting to n8n webhook: https://smartbotics.app.n8n.cloud/webhook/235904a4-7810-4bdb-a2b2-c35b7f9411e3
• JWT Authentication using secret: cica
• User context extraction from Supabase auth tokens
• Non-blocking webhook calls to prevent performance impact
• Three main functions:
  • handleError() - Main error handler that returns error response
  • wrapHandler() - Wrapper function for easy integration
  • logError() - For logging non-fatal errors

2. Updated All 18 Edge Functions

✅ Authentication & API:

• api - Main API router
• auth - User authentication

✅ OAuth Flows:

• oauth-shopify - Shopify OAuth integration
• oauth-woocommerce - WooCommerce API key connection
• oauth-shoprenter-init - ShopRenter OAuth init
• oauth-shoprenter-callback - ShopRenter OAuth callback

✅ Webhooks:

• webhooks-shopify - Shopify GDPR webhooks
• webhook-shoprenter-uninstall - ShopRenter uninstall handler

✅ Sync Operations:

• trigger-sync - Manual sync trigger
• shopify-sync - Shopify data sync
• woocommerce-sync - WooCommerce data sync
• shoprenter-sync - ShopRenter data sync
• shoprenter-scheduled-sync - Automated ShopRenter sync
• woocommerce-scheduled-sync - Automated WooCommerce sync

✅ Data Retrieval:

• shoprenter-products - Product data endpoint
• shoprenter-orders - Order data endpoint
• shoprenter-customers - Customer data endpoint
• get-ai-context - AI context retrieval

Error Details Sent to Webhook

{
  functionName: string,        // Name of the Edge Function
  errorMessage: string,         // Human-readable error message
  errorStack: string,           // Stack trace (when available)
  errorType: string,            // Error class name
  timestamp: string,            // ISO 8601 timestamp
  requestMethod: string,        // HTTP method (GET, POST, etc.)
  requestPath: string,          // Request URL path
  userId: string,               // User ID from auth token (if available)
  additionalContext: object     // Custom context data
}

Next Steps: Deployment

⚠️ IMPORTANT: The Edge Functions need to be deployed to Supabase for the changes to take effect.

Deploy all functions:

cd /home/claude/shopcall

# Deploy all updated functions at once
supabase functions deploy \
  api auth \
  oauth-shopify oauth-woocommerce oauth-shoprenter-init oauth-shoprenter-callback \
  webhooks-shopify webhook-shoprenter-uninstall \
  trigger-sync shopify-sync woocommerce-sync shoprenter-sync \
  shoprenter-scheduled-sync woocommerce-scheduled-sync \
  shoprenter-products shoprenter-orders shoprenter-customers \
  get-ai-context \
  --project-ref ztklqodcdjeqpsvhlpud

Or deploy individually if needed:

supabase functions deploy api --project-ref ztklqodcdjeqpsvhlpud
# ... repeat for other functions

Testing

Once deployed, errors will automatically be sent to the n8n webhook with JWT authentication. You can test by:

1. Triggering an error in any Edge Function
2. Checking the n8n webhook logs for incoming error reports
3. Verifying the JWT token and error details are correctly formatted

Commit

✅ Committed and pushed to repository: 3b9aef0

• All changes are in the main branch
• Ready for deployment

📋 Summary

All tasks completed successfully!

✅ Created centralized error handler utility
✅ Updated all 18 Edge Functions
✅ Committed and pushed changes (commit: 3b9aef0)
✅ Provided deployment instructions

The implementation is ready for deployment. All errors will now be automatically sent to the n8n webhook with JWT authentication as specified.

@fszontagh Please deploy the Edge Functions when ready to activate the error handling system.
