## Description
This update improves the handling of null values in action parameter
evaluation and rendering processes. Specifically, it ensures that null
values are treated appropriately, preventing unnecessary stringification
and Blob creation. This change enhances the robustness of the action
execution flow and prevents potential errors related to null values.
