Add a Trigger → Issue transitioned event

Add the following expression:

issuetype in subtaskIssueTypes()

Next to the JQL condition click on Add → Issue selector

Next to the Issue selector click on Add → Condition → Boolean condition

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

Finally, next to the Boolean condition click on Add → Action → Transition issue

After importing the JSON file, make sure to check the configuration of the rule. Non-existing configuration elements (issue types, fields, values etc.) will be highlighted.
