## Timeline of updates

- **resolved** 2024-06-25 16:15 UTC: Between 09:18 and 16:08 UTC, customers with no evaluation groups seeing NullPointerException errors in the SDK's, when pulling evaluation rules. In the scenario where a customer had 0 target groups the /client/target-segments endpoint returned the value null instead of an empty array \[\]. A change was made in the db layer of the backend to return an empty array rather than a not found error when no target groups exist for a customer. This had the impact of hitting a different codepath. This codepath copies all groups into a new array and changes some data before marshalling and returning the json response. Because no groups existed this copy would mistakenly end up returning a nil object instead of an empty array, which then got marshalled into the null json response. We can confirm normal operation. Get Ship Done! We will continue to monitor and ensure stability.
