Hello All,
I want to add due date on the new created task based on the start date of the Epic using automation.
I have tried the settings by JIRA to copy due date from Epic due date but seems even using this there is an error that I encountered.


For your information, I have set due date as a field in both epic and task type.
The next thing is to assign the due date from issue.parent.customfield_10015 (which is from parent Start Date) using JQL something like
{{issue.parent.customfield_10015.plusBusinessDays(5)}}
If you have succeed previously doing this, please let me know
