Dec 1, 2024

December 2024 monthly summary: Focused on reliability and configurability for Lollipop-based flows and downstream delivery. Implemented CloudFormation-driven timeout controls for Lollipop IdP and Assertion endpoints, with container-level environment variables to support longer durations. Added a header mapping utility to VersioningV1V23GetNotificationPrice to propagate authorizer context to downstream services. Fixed Lollipop SDK timeout issues by upgrading pn-commons (PN-9088). Across two repositories (pagopa/pn-external-registries and pagopa/pn-delivery), these changes improve end-to-end resilience and business reliability, reduce timeout-induced failures, and enable safer deployment of longer-running operations. Technologies demonstrated include CloudFormation templating, container configuration via environment variables, and header-level request enrichment.
