Oct 1, 2024October 2024 — Countly/countly-server: Implemented robustness and observability improvements through two critical fixes. Job Runner now uses an abstracted collection interaction, standardizing database calls and reducing runtime errors. FCM push notification error handling enhanced to log and preserve SDK errors even when the internal error mapper is unavailable and to include SDK code/messages when missing. These changes improve stability in production, simplify troubleshooting, and reinforce developer confidence in the Job Runner and Push paths.
