Summary for May 2025 (repo: weni-ai/flows): Key delivery focused on enhancing data processing reliability, API robustness, and developer efficiency. The month delivered major features, bug fixes, and infrastructure upgrades that collectively improve business value and platform resilience. Key features delivered: - Datalake integration and message template consumption enhancements: Introduced a configurable datalake server address and refactored message template consumers; adjusted consume method signatures by removing the no-cover directive to improve testability and align with coverage tooling, enabling more accurate runtime configuration for message processing. - WhatsApp Broadcast Write Serializer validation updates: Strengthened validation rules for WhatsappBroadcastWriteSerializer, including enforcing action_type in the payload and updating typing_indicator usage; updated tests and release notes accordingly. - Internal Messages API endpoint development and tests: Built a new internal API endpoint to retrieve messages, with authentication, permissions checks, filtering, and pagination; refactored serializers and views to reduce duplication and added comprehensive tests. - Open Ticket API error handling with MailroomException: Improved error handling by explicitly catching MailRoomException, returning appropriate HTTP statuses, and centralizing exception handling for clearer client-facing errors; tests updated. - Dependency upgrades and release notes: Upgraded core dependencies (weni-rp-apps), added weni-datalake-sdk, and updated version bumps in pyproject/poetry.lock; release notes documented serializer-related changes where applicable. Major bugs fixed: - Open Ticket API: Centralized MailRoomException handling and improved error responses with clearer status codes; existing tests adjusted to reflect new behavior. - General test stability: Updated tests across serializers and endpoints to reflect new validation rules and error handling, reducing flakiness and aligning coverage tooling. Overall impact and accomplishments: - Increased configurability and testability of the data processing flow, enabling faster iteration and more reliable deployments. - Strengthened API reliability and client-facing error messaging, reducing downtime and support load. - Better developer experience through reduced duplication, clearer tests, and up-to-date dependencies and release notes. Technologies/skills demonstrated: - Python/Django REST framework, serializers, viewsets, and authentication/permissions. - API design with filtering, pagination, and robust error handling. - Test-driven development, test coverage improvements, and CI-readiness. - Data lake integration patterns and SDK usage, plus dependency management (poetry/lockfile) and changelog maintenance.
