feat: Return null on accessing a non-existing property #709

Closed saig0 closed 10 months ago

saig0 commented 10 months ago

Description

Change the behavior for accessing a non-existing property. Instead of failing the evaluation, it returns null. A failure with a descriptive message is reported.

This change is aligned with the DMN specification and the new direction to be more null-friendly.
