Refactor Phase 3 Batch 2–4 Novu-related functions to use the createEdgeFunction wrapper, replacing explicit HTTP servers with edge wrapper, adding standardized logging, tracing, and error handling across subscriber management, topic/notification, and migration/sync functions.
Consolidate CORS handling by introducing a shared supabase/functions/_shared/cors.ts and migrate edge functions to import from it. Remove inline cors.ts usage across functions, standardize headers (including traceparent and x-request-id), and prepare for environment-aware origins.
Add centralized errorFormatter to convert various error types into readable messages, and apply it across edge functions. Replace String(error) usage with formatEdgeError, update relevant imports, fix a throw to use toError, and enhance logger to log formatted errors. Includes new errorFormatter.ts and widespread updates to 18+ edge functions plus logger integration.
Refactor PhotoUpload component to fetch session token before polling, enhance error handling in NotificationService and versioningHelpers with `instanceof Error` checks, and add comprehensive validation for request body fields in the create-novu-subscriber Supabase function.
