Confluence has been updated to version 6.15.9

This article shows how to synchronize an assignee to a text custom field. 

Source side

 Outgoing sync 

  replica.assignee = issue.assignee


Destination side  

An assignee is an object with some properties. Each property is of type text. You can sync the following properties: key, email, displayName, username. 

 Add the code below to the Incoming sync to sync Assignee email address

 issue.customFields."Your custom field name".value = replica.assignee.email

You can replace the .email property with any other assignee object property.
Check User for all available properties.

For example, to sync the assignee displayName use this code

 issue.customFields."Your custom field name".value = replica.assignee.displayName
