Accepted Solution Posted: 1 year agoCarissaW_GCS PEGA replied to nvuyyuruChanges were made so the parameter name and value are now required. There is backwards compatibility in place so the existing rules will still run; however, when modifying the rules then you will be required to provide the parameter name and value.
