Getting error with Reverse termination conditon

Summary:

We have requirement to configure different approvals for reverse termination and termination

we need to trigger the different approval flows based on action.

I'm attaching the screenshot of error below we are getting for termination condition.

we are getting {{null}} for sensorprocessname and also I tried with sensorprocesscode null value is coming.

we are following the below codes for but they are not working.

Does have idea on how to set up different approvals for Termination, Reverse Termination , Resignation and withdrawal resignation. And also If the associate withdraws resignation one approval should come, If the HR do the reverse termination then another approval flow should come.
