{{Debugging analysis:}}
{{Seems like its related to instance variable inheritance and visibility scope
of instance variables in TransformMaintainer class. As per error, its seems
like {{TransformMaintainer#buildRowDeleteMutation}} was called.
{{buildRowDeleteMutation}} is defined in parent class: {{IndexMaintainer}} and
is trying to access to access private instance variable:
{{{}emptyKeyValueCFPtr{}}}. As the instance variable is declared in both the
parent and child classes and is private in both so,
}}{{{}{{IndexMaintainer.emptyKeyValueCFPtr gets used which is null while
TransformMaintainer.emptyKeyValueCFPtr is not non-null.}}{}}}{{{}{}}}
{{{{Additionally, TransformIT tests need to fixed as they have test cases for
this scenario but are broken currently and not running in master branch
pipeline due to missing Category annotations.}}}}
