Hello together,
we don't get it working that Jira Automation sets the assignee of a new created issue to the person that we want.
To be more precise:
We have ticket A - parent of ticket B.
Ticket B triggers automation rule by transition to specific status.
Ticket C is being created in this automation rule.
So, we want that Ticket C gets the reporter of Ticket A as assignee when the rule gets triggered by Ticket B.
We tried it with smart values, e.g. {{triggerIssue.parent.reporter}} or {{triggerIssue.parent.reporter.DisplayName}}, but we always get the error message:
Unknown fields set during create, they may be unavailable for the project/type. Check your custom field configuration. Fields ignored -
Assignee (assignee)
Please see our automation rule here:
Yes it sounds complicated... it is!

We hope you can help us
