the following document (stripped down MWE):

%%% test.tex %%%

  if font and font.fonts and font.current then %
    local f = font.fonts[font.current()]%

%%% test.tex %%%

throws the error on the console:

%%% console %%%
error: ...r/texmf-dist/tex/luatex/luaotfload/luaotfload-merged.lua:7542:
attempt to perform arithmetic on local 'factor' (a nil value)
l.12 \setbox0\hbox{To}
%%% console %%%

What is the problem?

The .log file contains:

%%% test.log %%%
{restricted horizontal mode: the letter T}
{the letter o}
{end-group character }}
l.12 \setbox0\hbox{To}
%%% test.log %%%

And the version list:
