Currently, if issues that triggered automation rules is no longer valid (deleted or archived), the error message that the execution shows is the following:

"The rule actor doesn't have permission to view the event that triggered this rule"

This message is misleading and don't provide enough information for Admins to understand which work item should have triggered the rule. 

Improving the error message when such scenarios happen would greatly help Jira Admins on easily spotting the errors for issues that are no longer valid and triggered errors in the executions.
