Hi,
I am trying to create a Jira Automation that adds the Epic FixVersions value to all its epic children, while keeping the existing Epic children FixVersions value.
Here is what I have so far:

When I run the automation, I get this error:
Error editing issues
(Specify a valid value for FixVersions (fixVersions))
Does anybody know how to adjust the JSON to make this work?
Thanks!
