If Ganesh, Tejal, and Pradnya logged the time on the Jira server ticket then working should log as Yogesh user/author on the Jira cloud ticket.

And except for these three users if anybody logged the time on the Jira server ticket then the worklog should log as admin user/author on Jira cloud ticket.

For the same, I have gone through the below Exalate article and added code to the destination (Jira cloud) incoming sync for existing issues but it's not working as expected.

https://docs.idalko.com/exalate/display/ED/Worklogs+synchronization

but Every time it's logging the time as Yogesh author on Jira cloud, irrespective of the user who logged the time on Jira server.

final def userMapping = [
       "pradnya" : "yogesh",
       "tejal" : "yogesh",
       "ganesh" : "yogesh",
       "boudewijn" : "admin"
]
issue.workLogs = workLogHelper.mergeWorkLogs(issue,replica, { w ->
   w.author = nodeHelper.getUser(userMapping[w.author?.email]) ?: w.author
   w.updateAuthor = nodeHelper.getUser(userMapping[w.updateAuthor?.email]) ?: w.updateAuthor
   w.comment = "auto-synced worklog from Brain2"
})
