I'm currently trying to create a trigger to copy a custom text field on a ticket into a custom user field. When I use the following placeholder as the value to set user field to on the action, it doesn't treat the placeholder as a variable, and instead literally copies this text into the user field:
{{ticket.ticket_field_4971504499091}}
See below for a screenshot of what I'm trying to do:



Unfortunately, placeholders aren't useable as the values when creating triggers. Your use case might be something our product team would be interested in hearing about – would you mind creating a post in our Feedback - Ticketing System (Support) topic, using this template?
