No caption numbers in docx output about pandoc-fignos HOT 4 OPEN

I have the same problem. I noticed it when trying to work out why I was getting "Bad reference" errors. Finally noticed that none of the figures were numbered, which is why the reference was bad. This wasn't happening a couple of weeks ago. We're preparing a report and have been running the same command many times over the last few weeks. In case it's relevant, around the same time I got this error when running the command:

<userpath>.pyenv/versions/3.9.7/envs/pandoc/lib/python3.9/site-packages/pandocxnos/core.py", line 179, in _get_pandoc_version
    raise RuntimeError(msg)
RuntimeError: Cannot understand pandocversion=3.1
Error running filter pandoc-fignos:

This can be fixed by manually changing core.py as @nandokawka writes here. It seems more than a coincidence that the figures stop appearing around the same time as this error.

I have changed core.py, but the error still exist.

Same issue with

pandoc 3.1.1
Features: +server +lua
Scripting engine: Lua 5.4

If you refer to the figure you get pandoc-fignos: Bad reference:

from pandoc-fignos.

Maybe this could help in finding a bugfix. I'm running into similar issues when trying to generate LaTeX or HTML output. From some very rough debugging attempts I'm getting the feeling, that these "free standing" images are not properly processed by the fignos filter.
When you add a non-breaking space at the end of such an image (notice the \ at the end of the line):

![map](C:\Pandoc\map.png){#fig:map_id}\

you can get rid of the Bad reference: error. The same happens when you add some text in front.
