Copy from note to YAML property

What I’m trying to do

I have meeting notes that include a section titled Attendees, where I link to individual people notes. I’d like to automatically copy the list of linked people from this section into the Attendees property in the YAML frontmatter.

Things I have tried

  • Created a Templater user script (sync_attendees_to_yaml.js) to extract [[linked attendees]] from the note body and update the YAML frontmatter.
  • Attempted to trigger it via a Templater button inside the note → caused crashes during note creation.
  • Tried using the Buttons plugin to run the script → plugin error prevented button execution.
  • Switched to QuickAdd, created a macro to run the script → found QuickAdd cannot run Templater .js user scripts.
  • Tried inserting the logic into a .md file as a Templater template → it pasted code instead of executing.

Appreciate any help that can be given
