TransformationLogic in ServiceNow Data Flow

Has anyone used the “TransformationLogic” tag in the IntegrationServicesConfig.xml?

I’ve tried variations of upper(), Name.upper(), upper etc … but i continue to get errors.

name.upper()

With the error:
2021-11-23 15:16:01,814 - IDataLoader - ERROR - Error Processing Transformation: xxx00431
2021-11-23 15:16:01,814 - IDataLoader - ERROR - Error Processing Transformation: name.upper()
2021-11-23 15:16:01,814 - IDataLoader - ERROR - Error Encountered while transforming: name ‘name’ is not defined

@aram can you comment?
