Push custom field from epic to child tasks

Question

I am working on a JIRA automation for a team-managed project where a specific dropdown style custom field is in both an epic and its child stories/tasks.

I can trigger the event properly, its grabbing the right child tasks, but I'm getting invalid JSON errors on the Edit issue fields action:

{
"fields": {
"customfield_11354": {{"issue.customfield_11354"}}
}
}

customfield ID number was obtained from issue settings > custom fields > [my custom field] > looking at the URL.

I've also tried:

"customfield_11354": {{"issue.customfield_11354.id"}}

"customfield_11354": {{"issue.customfield_11354.value"}}

"customfield_11354": {{"issue.customfield_11354.name"}}

Thanks

Because I was within a "for loop" for each of the epic's stories and other children, the following is the correct usage:

{
"fields": {
"customfield_11331" : { "id" : "{{issue.parent.customfield_11331.id}}" }
}
}
