Automation for Jira - Copy from trigger issue JSON

[Jimmy]

I'm using Automation for Jira in tandem with Dynamic forms and the custom fields do not appear under the "Choose field to set" filter. My goal is to copy the trigger issue's value for certain fields, but my code isn't working:

{
"fields": {
"TEST D: Project Closure Type": {"value" : "{{triggerIssue.TEST D: Project Closure Type}},
}
}

I was able to straight update the field with whatever choice I want, but I can't figure out how to copy from trigger issue.

wondering whether anyone get this to work?

I'm having a similar issue. Did you ever get it to work?
