Worked on stabilizing the search and scoring functionality in the wazuh-indexer repository by addressing a critical NullPointerException within the ScriptScoreQuery component. Applied backend development skills in Java to ensure that scoreSupplier.get() consistently returns a non-null scorer, thereby reducing runtime errors for users relying on custom scoring logic. Enhanced reliability by expanding unit test coverage around the affected code path and updating the public changelog to document the fix and its impact. This targeted bug fix improved the platform’s resilience, lowered mean time to resolution for related issues, and reinforced the robustness of search operations within the Java-based backend system.
