Worked on the City-of-Helsinki/tilavarauspalvelu-core repository to resolve a critical issue affecting Sentry error attribution and source maps uploads. Addressed a bug where mismatched release names between the UI and Admin UI led to misattributed errors and unreliable debugging. Implemented a solution by prefixing release names with service identifiers, ensuring alignment with recorded events and improving the accuracy of error tracking. Utilized YAML for configuration changes and applied CI/CD and DevOps practices to streamline the deployment process. This targeted fix enhanced debugging efficiency, enabling faster incident triage and reducing the effort required to trace and resolve production issues.
