November 2024 (2024-11) monthly wrap-up for proofcarryingdata/zupass. A focused set of backend and frontend improvements delivered to stabilize authentication, improve ticket issuance, expand ticketing capabilities, and enhance Pretix integration, while also addressing a Devcon-specific background sync edge-case. Key outcomes include robust login routing, product ID validation, multi-add-on ticket support, improved issuance flow with clearer error handling, and refreshed UI integration. What was delivered: - Authentication and login flow cleanup: Reverted changes around login query params and redirects; ensured unauthenticated users are redirected to login; stabilized routing and session management in the passport client. - ZKTG: Product ID validation: Added productId option to Zupass Ticket Generation; validates submitted product ID against the expected product ID for the Telegram chat; refactors proof generation to include productId when available. - Zupass: Multi-add-on tickets support: Enhanced handling of add-on tickets; updated one-click page to display/manage multiple add-ons; backend PretixPipeline now correctly links add-on tickets to their parent tickets. - Issuance flow improvements and error handling: Refactored generic issuance routes to improve error handling and ticket display; shows an error page if no main tickets are found and counts only main tickets for display; updates error page button text for better UX. - Pretix integration enhancements: Styling updates, refined email propagation logic, support for product variations, and ticket image/branding options. - Background sync fix for Devcon edge-case: Fixed a perpetual loading state for users without a Devcon ticket by correcting the sync settlement logic and extra fetch handling.
