Re: [NTG-context] Error: attempt to index a nil value

      ...
I was suggested a long ago to hack the file
  /usr/local/texlive/2021/texmf-dist/tex/generic/context/luatex/luatex-math.tex
and use LuaTeX directly, now using Version 1.13.2 (TeX Live 2021), but I get this error:
(./luaotfload.sty
(/usr/local/texlive/2021/texmf-dist/tex/latex/base/ltluatex.tex))
(./luatex-math-modified.tex[\directlua]:1: attempt to index a nil value (global
'arguments')
stack traceback:
  [\directlua]:1: in main chunk.

It is from this segment in the modified luatex-math.tex:
\ifdefined\directlua
    \directlua {
        if arguments["mtx:lucidabright"] then
            tex.print("\string\\lucidabright")
        else
            tex.print("\string\\latinmodern")
        end
    }
\fi
Is there a workaround? —I may ditch this setup in favour of using 'context' directly, so it is not so important if there is no fix.
I have no clue .. it looks like you load a latex style so I suppose that 
'arguments' is no longer defined there (as it worked for you in the

past). Maybe 'arguments' lives in some namespace?

  \directlua {for k, v in pairs(_G) do print(k.v) end}

This will show you what is in the global namespace, maybe 'arg'?
