trying to set assignee based on custom field via script runner

[tom webb]

using built in scripts : setting custom field value to another field against the filter i have set however i cannot figure out the correct id for 'assignee' i have tried just assignee however im not sure if i need to set it to something like system_assignee etc.. does anyone know?

not wanting to do it on post function just wanting to run a clean up script.

issue.assigneeId = "someone"

but you need to give more context, I don't know if you're using IssueService or what all.

Try:

• issue.assignee
• issue.assignee?.displayName
