Summary

The automation system recognizes the rule initiator as an inactive user, leading to the display of the following message. Consequently, the rule action is not executed, although the rule appears as "passed" in the audit log for the rule.

Environment

Jira Cloud
Automation for Jira

Solution

There are various places within Jira, including automation, where the display name will not work to choose a user.

To achieve your goal, instead of using {{initiator.displayname}} please use the following smartvalue: 

{{initiator}}
