Automation rule fails: "Issue event trigger could not retrieve this issue for further processing"

[Erik Vanderstraeten]

We have an automation rule like screenshot below.
The aim is to inform support agents to follow communication on linked issues from another project (fyi: those were escalated to another team).  We added automation that would copy a comment from one project to another, but it actually never worked.
When it should copy a comment, it already fails on the trigger step "When: Issue commented" with : "Issue event trigger could not retrieve this issue for further processing"

In Rule Details, we did specify "restrict to projects: WHSSUP and BIT"
+ Actor = user who triggered the event (or Automation for Jira if there aren't enough permissions)

Anybody understands why Jira Automation isn't able to retrieve the issue?

Hi Erik,

Try using {{triggerissue.comments.last.body}} when you add the comment. 

[John Funk]

Oh, and use {{triggerissue.comment.last.author.displayName}} to show the author.

[Erik Vanderstraeten]

Thanks John.
I just tried it again and {{comment.author.displayname}} and {{comment.body}} seems to work fine.  (As does your suggestion)

Note: while testing I couldn't reproduce my issue; I'll keep an eye on it the next days.

Today I had the same issue again.

Note: I have 2 similar rules (only difference is a link to another project).

I made your suggested change to one of the two rules.

Today, both rules failed again (for the same BIT ticket; which doesn't have any linked issue).
Thus your suggestion is not helping unfortunately

[John Funk]

Can you share the audit log where it failed? 

[Erik Vanderstraeten]

Hi John,

of course, here you go:
(FYI: BIT-559 is not of the SUAT project and doesn't have any linked issues)
