[NTG-context] TeX Live 2019: attempt to call a nil value (upvalue 'isfile')

Dear list, I just installed TeX Live 2019 pretest and running context --make fails with error in callback: ...xlive/2019/texmf-dist/tex/context/base/mkiv/luat-cod.lua:194: attempt to call a nil value (upvalue 'isfile') This can easily be fixed by replacing in luat-cod.lua local isfile = lfs.isfile with local isfile = function(file) return lfs.attributes(file,"mode") == "file" end This should probably be fixed before the release. Cheers, Henri
