Hope null check option fot Assign Activity

Mainly due to business exception issues, the process of storing values ​​in variables may not work correctly. (null)
If the process transitions to the next stage in this state, an error will occur stating that the value specified for the activity parameter is invalid when the variable is used.
If an error occurs in this location, it will take time to investigate the cause of the error.
In the variable assignment activity, I would like an option that would cause an error if the input value is null.
