Can I access "system" columns in a word template

[muellerfelix]

I am trying to insert related data from a list and library control to into an Word document (I used following instructions: https://plumsail.com/docs/forms-sp/how-to/docx-to-pdf.html).
If I want to access standard columns from my related list there is no problem but if I want to access system columns i can not get int working.
This is my JSON:

This is my template:

And this is the result:

I think the problem is the {} but I am not sure how to mask it. Do you have any idea?
