Hi,
To generate my documentation, I use a toolchain that generates a markdown
file from various sources, the last step is the generation of Confluence
HTML via Pandoc. Since Pandoc does not directly support Confluence HTML, I
use a patched version of
https://github.com/jpbarrette/pandoc-confluence-writer (patched because the
generated HTMl is not always quite correct and some features I need are
missing). This worked well for a long time, but after the last update (from
Pandoc 2.19.2 to 3.1.8) I got a series of warnings:
*WARNING: Undefined function 'Figure'WARNING: Undefined function
'Figure'...*
and the HTML code for the images is completely missing. I tried Pandoc
3.1.9, same result. Confusing: the Lua code of pandoc-confluence-writer
does not contain a call to a function named "Figure". Just to analyze the
problem, i tried custom-markdown.lua from
https://gist.github.com/tarleb/5a9c3fbfa47b0e6d3643efd8af2994b9 and i got:
*Error running Lua:custom-markdown.lua:19: No function to convert Figure
(Block)*
What's going on? Is this a bug in Pandoc? Is there a workaround?
At the moment I will be using version 2.19.2, but I would like to be able
to upgrade to newer versions of Pandoc.
Minimal example:

The Figure element was added in 3.0: search https://pandoc.org/releases.html
for "Support complex figures" for full details.
So I think that your Confluence writer needs to be updated! I see that it
has a CaptionedImage function and suspect that this will no longer be
called, and that the needs-to-be-added Figure function will get called
instead, but probably not with exactly the same arguments.
Are you OK with hacking this? I don't mind having a go if not... let me
know!

Something like this should work? The change to attributes() is a hack to
use 'data-scale' rather than 'scale' and the change to Image() is to insert
the alt text and the attributes. The main change is the new Figure()
function (oops... I see that I'm ignoring its attributes).

Oh sorry, I didn't use the CaptionedImage() code... but I'm sure you get
the idea.
