Hi,
 
To generate my documentation, I use a toolchain that generates a markd= own file from various sources, the last step is the generation of Confluenc= e HTML via Pandoc. Since Pandoc does not directly support Confluence HTML, = I use a patched version of https://github.com/jpbarrette/pandoc-c= onfluence-writer (patched because the generated HTMl is not always quit= e correct and some features I need are missing). This worked well for a lon= g time, but after the last update (from Pandoc 2.19.2 to 3.1.8) I got a ser= ies 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 no= t contain a call to a function named "Figure". Just to analyze th= e 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 t= o upgrade to newer versions of Pandoc.
