I suspect the double quotes are part of file names, hence files cannot be found. Perhaps try remove them in macro argument.
Hope this helps

Dear List!

THis MWE must be faulty, but where is the error?



userdata = userdata or {}

function userdata.file_exists (name)

   local name = name
   local f    = assert ( io.open ( name, "r" ))

   if f then
      f:close ()
      context ( name )
      context ( "  exists!" )
      context ( name )
      context ( "  doesn't exist!" )




\lookupfile{"$HOME/context-tests/AAA.lua"}	% "AAA.lua" intentionally does    exist
\lookupfile{"$HOME/context-tests/BBB.lua"}	% "BBB.lua" intentionally doesn't exist



It makes no difference in commenting out the first or the second "\lookupfile" command.
The error message eventually is always nearly the same:

token call, execute: [ctxlua]:8: "$HOME/context-tests/AAA.lua": No such file or directory
token call, execute: [ctxlua]:8: "$HOME/context-tests/BBB.lua": No such file or directory

I'm using:
LuaMetaTeX, Version 2.00.0 
ConTeXt  ver: 2019.10.10 18:15 MKIV beta  fmt: 2019.10.12  int: english/english

Please, any ideas?
