Structure v8.1.2 - Change History Item property reference not working

[Ryan Campbell]

I want to show the last date/time Fix Version/s was updated.  I'm trying to use Change History Item Property reference in a formula, but it's not working.  I don't get an error message.  It's just blank.  Here's one example of what I've tried that is not returning anything on an issue that has a Fix Version/s.

history.changes
.FILTER($.field = "fixVersions")
.LAST()
.changeGroup.timestamp

I confirmed that we are on Jira Software Data Center and Server 8.20.  Also, I can get the HISTORICAL_VALUE formula to work, was part of the same release.  That leads me to believe I should be able to write a formula to get the last time Fix Version/s was updated.

I figured it out.  I changed the variable name to "History1", and then manually mapped it to the correct Structure attribute, which was the second instance of "History".  Now, it's working!

Please note:  I just found out that we have a custom field in Jira that is called "History".  It does appear that Structure is automatically mapping the variable in my formula to that custom field.  Is there a way to remove that mapping and have it map to the Structure item "history"?

Hi, @Ryan Campbell. Welcome to the community 👋

First, congrats solving your own question. I think I may be trading messages with a future "Structure Ninja." 

But, I just noticed the "hidden" question contained in your second, accepted answer. I'm afraid that's going to be missed by most ppl here (because it's contained in an answer that's marked "accepted."   That would suggest there are no more questions to most ppl here.

Anyway, in this case, I think your best bet would be to reach out to the Structure support team directly. You will likely get a quicker answer that way. 

Hope this helps,
