[NTG-context] fontloader error in latex: attempt to call upvalue 'getdirection' (a nil value)

7 Jan 2019

      I just tried to import the fontloader from 2019-01-03 into latex,
and get on a simple document the error

 (./test-utf8.aux)error:
...ad/texmf/tex/luatex/luaotfload/fontloader-2019-01-03.lua:23868:
attempt to call upvalue 'getdirection' (a nil value)
.
\newpage ...k \@nobreakfalse \everypar {}\fi \par
                                                  \ifdim \prevdepth
...
\z@ \vs...
l.51 \end{document}

I have no idea (yet) if this is latex specific or if it could affect
context too but thought I better mention it. The line refers to this
part of the code:

  pardirstate=function(start)
    local nxt=getnext(start)
    local dir=getdirection(start) --<--
    if dir==lefttoright then
      return nxt,1,1
