can you confirm what's in line 38 of the writer? if you haven't edited the
file then it's this
<https://gist.github.com/wlupton/2fc23fc1c4e4b4899121bfafc0fea4bf#file-html-multi-writer-lua-L38>
:

local output_file_dir, output_file_base = utils.path.split(output_file)

can you confirm that you've also copied utils.lua and that it's being
found? it should be calling the function at this line:
