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?

There is a good explanation about the permissions on Jira On Demand. Hope it helps!
