Hello,
We want to only allow certain users to modify the Sprint field i.e. add/remove a issue to/from a Sprint and restrict it for other users.
I know it can be solved by just communicating internally b/w the different departments, but since that is not working and users are changing the Sprint field however they like; I want to allow editing of Sprint field only to certain users.
Hence, I set up an automation as below:

However, I keep getting the below error

I went through a lot of articles in the Community and tried everything I could find. Could someone help me with fixing this?
