Forward last public comment from child to parent ticket with "real" attachments

Hello @all,

i would need some help with an automation rule that forwards the last public comment (or reply) with real attachments, if any, from a child ticket to a parent ticket.

I got it to work but what i have problems with are the attachments. If i use {{ticket.last_public_comment}} as a placeholder i get the last comment and links to the attachments if there were any. If i add {{ticket.attachments}} nothing changes. This placeholder seems to do nothing.

Isn´t there a way that i get real attachments forwarded? Is there another placeholder that i don´t know of?

This is  what i have so far:

Thanks for your help!
