Batch 1 of Phase 2: migrate 3-4 edge functions to use createEdgeFunction wrapper (process-selective-approval, process-selective-rejection, rate-limit-metrics) to enable automatic error logging, CORS, auth, and reduced boilerplate; preserve existing logic where applicable and prepare for subsequent batches.
Enhance error handling and logging across all edge functions:
- Introduce a shared edgeFunctionWrapper with standardized error handling, request/response logging, tracing, and validation hooks.
- Add runtime type validation utilities (ValidationError, validators, and parse/validate helpers) and integrate into edge flow.
- Implement robust validation for incoming requests and known type mismatches, with detailed logs and structured responses.
- Add post-RPC and post-database error logging to surface type/mismatch issues early.
- Update approval/rejection entry points to leverage new validators and centralized error handling.
Read idempotency key from headers in process-selective-approval and process-selective-rejection, remove it from request bodies, add header validation, and redeploy edge functions to fix idempotency flow.
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.
Apply quick wins and pipeline fixes for integration tests:
- Remove is_test_data flag from location inserts
- Increase test delay from 2.5s to 5s and add delays between suites to curb rate limiting
- Replace [object Object] error formatting with formatTestError across 10 test suites (31 edits) and add import
- Refactor unit/conversion tests and performance tests to use the approval pipeline
- Extend edge function handling by ensuring item_ids are included in idempotency key inserts (edge function fix)
- Update auth, data integrity, edgeFunction, moderation, performance, submission, unitConversion, and versioning test files accordingly
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.
Implement distributed tracing across edge functions:
- Introduce span types and utilities (logger.ts enhancements)
- Replace request tracking with span-based tracing in approval and rejection flows
- Propagate and manage W3C trace context in edge tracking
- Add span visualization scaffolding (spanVisualizer.ts) and admin TraceViewer UI (TraceViewer.tsx)
- Create tracing-related type definitions and support files
- Prepare RPC call logging with span context and retries
Enhance edge functions process-selective-approval and process-selective-rejection with edgeLogger-based, structured logging. Introduce request tracking (startRequest/endRequest), replace all console logs, add comprehensive logging points (auth, payload validation, idempotency, RPC calls, deadlocks, errors, locks), and register process-selective-rejection in config.toml. Also sanitize sensitive data in logs and ensure duration metrics are captured.
- Adds atomic rejection transaction edge function and RPC
- Updates moderation client to use new rejection path
- Introduces rejection transaction migration and supporting readouts
- Moves photo-related approval handling toward RPC-based flow
- Lays groundwork for idempotency and resilience in moderation actions
