Assign an issue to the last assignee on a transition

Use case

When an issue is transitioned to the DRAFT status, the issue will be automatically re-assigned to the last assignee from the project role "Developers".

Should I use an automation rule or a workflow post function?

When to use this automation rule and when to use a workflow post function?

This use case is very useful if you need to re-assign issues across different projects and issue types.

If you only need to re-assign issues in one dedicated project or issue type context, using the Assign to project role workflow post function might be the better alternative.

⚒️ Configuration

Issue transitioned event

Create a new rule and name it appropriately.

Providing a description will help you to identify what the rule does but this step is optional.

Add a Trigger → Issue transitioned event

Boolean condition

Add Boolean condition and enter the following Parser Expression*

Bash

%{trigger.issue.status} = "Draft"

Boolean expressions are logical constructions that return true or false.
In this use case, the expression will only return true if the status of the issue triggering the rule is DRAFT .
