Live Demo does not seem to fully decode uploaded fig file

[moeffju]

I have a fig file where I want to manually merge fill styles of various objects. Evan's https://madebyevan.com/figma/fig-file-parser/ gives me a canvas.fig pseudo-file with keys such as guid, type="document", children with type=CANVAS, etc. However, it does not have a way to re-compile a .fig file from the JSON.

Uploading the same file to the live demo gives me a JSON output of a "root" element with type NODE_CHANGES and a lot of edit history, but none of the same data Evan's tool gives me. (On the other hand, Evan's tool does not extract the NODE_CHANGES, but since I'm not interested in them, I don't mind.)

Unfortunately the file contains some proprietary stuff so I cannot just attach it here, but maybe the bug is already known or evident from the description. I'm happy to answer questions and try things as well.
