The JSON Null Utils component was created to provide a possible solution (or at least some alternatives) on how to handle null values in JSON data in OutSystems. The basic strategy this component relies on is creating an extra auxiliary boolean field for each attribute that indicates whether the attribute is null or not.

While this issue can be abstracted to any JSON data, this component was created to handle null values when exposing and consuming REST APIs in OutSystems with JSON requests/responses.
