How to update sub-task parent with automation?

Question

Hi! Is there a way to update parent issue of a sub-task via automation? Found similar questions but they seem to be relevant for epic links. I tried this (as described here), but it doesn't work although the rule says it's completed successfully. Tried with id instead of key also, no change.

Thanks for any help!

I added a comment to that issue. Guess that's all I can do for now, thanks for all the help Trudy!

I suspect it is not possible to change the parent of a sub-task via automation on Jira Server/DC. I found that there is an issue for Jira Server that is similar to the one you found for Jira Cloud.

https://jira.atlassian.com/browse/JRASERVER-68763

So far I have not found any references that show how anybody was able to accomplish changing the parent of a sub-task through automation.

Hi, thanks! Indeed that post was for Cloud, I missed that :/  I don't think we are using Cloud. I also checked the Audit as you suggested and after all it contains errors, which is weird because when running the rule a small popup tells me it completes successfully:

The Audit complains that parent field does not exist.

I am pretty sure I got the components right because the email sent contains correct values for issue keys. Do you know if there is any way to achieve what I want with a non-Cloud solution?

Sorry for all the newbie mistakes I only started my adventure with automation today :/
