Problem

Hi, I’m having trouble creating my own invoice template. I want the invoices to display information about the project they’re associated with, and everything seems fine in the template designer.

But when I run the template on a real invoice the project information simply doesn’t show up.
This is the result of the PDF after running

Is this something I’m doing wrong? Or is it a bug?
I ran the template in the web demo and the same problem occurs.

Help please, I’m stuck

Hi,

I suggest asking in a discussion on GitHub

I will do so, thank you
