In "Add postfunction" section there is no "Update Custom Field", only "Update Issue Field". When I choose this option, there is no field "Epic Status" in the Issue field dropdown.
I've checked this with 8.0.2 and 8.1.0 versions.
Can you give me an answer which versions are suitable for this article?
BTW, I can develop my own postfunction and I don't want to use any plug-ins to solve my problem
