## Updates from Split (Harness FME)
### 2026-04-28 18:27 UTC: resolved
Requests made by SDKs with Rule Based Segments support could have gotten a null instead of an empty for responses with no Rule Based Segments, leading to an null pointer exception. 
Impact observed: 18:27 until 19:05 UTC. 
The impact for SDKs would have been a failure to initialize or process an update. Any change made to feature flags or RBS in an affected environment would re-generate any specific caches remaining.
