I'm attempting to create an automation that sets due dates for each of an issue's subtasks by referencing the due date (or other custom date field) in the parent task and a date 'offset' value from a custom number field in each subtask. Our use case is that such a task/subtask scenario could be used as a template for subsequent task/subtask instances and the due date of each subtask could then be updated by simply updating the single due date in the parent task.
My thinking was that I would use something like this:
{{#=}}{{issue.parent.duedate}} - {{issue.Visit date offset}}{{/}}
but this throws errors and obviously I'm missing the point.
I'm no coder, and that's likely clear to anyone that is, so bear with me as I explore automation options. Any help is appreciated!
