error rendering PDF

[poldrack]

When I try to render the pdf (using the default _quarto.yml) I get the following error:

Error running filter /home/poldrack/Dropbox/code/quarto-cli/src/resources/filters/main.lua:

This is the relevant section in boxes.lua:

-- wrap element in \begin{env}[opts] and \end{env}
local function wrapEnv(el, env, opts)
  local beginEnv = pandoc.RawInline('latex', '\\begin{' .. env .. '}[' .. opts .. ']\n')
  local endEnv = pandoc.RawInline('latex', '\\end{' .. env .. '}\n')
  table.insert(el, 1, beginEnv)
  table.insert(el, endEnv)
  return el
end

I'm not familiar with the pandoc extensions so I'm not quite sure how to debug this, but I wonder if I have a different version of pandoc such that pandoc.RawInline is returning a Block rather than a table? (I'm using pandoc 2.9.2.1 on Linux).

A different pandoc version seems like a plausible explanation for the error -- I'm running pandoc 3.1.5.

[poldrack]

upgrading to the latest pandoc (3.1.8) didn't solve the problem. where does _extensions/pandoc-ext/boxes/ come from? I don't see it in the pandoc extensions (https://github.com/pandoc-ext), was hoping to check there for issues.

(sorry for accidentally closing :-)

[mikabr]

It's a custom extension that we wrote, so unfortunately you won't find any helpful information anywhere :P Another difference could be the version of quarto you're running? I'm on 1.3.433.

[poldrack]

ok, confirmed that the the error with block.lua does not occur using 1.3.433 on Linux; the problem seems to be with the more recent development version. I'm still having trouble rendering the pdf due to latex compliation issues, but I"ll close this issue and open another if I can't figure that out.
