Description

If a flowfile 'filename' property includes a path (i.e. nested subdirs), then PutFile fails due to improper creation of temporary write file.

Example ExecuteScript lua to update filename:

function onTrigger(context, session)
  flow_file = session:get()
  log:info('rename_file triggered')

  if flow_file ~= nil then
    file_name = flow_file:getAttribute('filename')
    new_file_name = 'a/b/' .. file_name
    log:info('renaming ' .. flow_file:getAttribute('filename') .. ' to ' .. new_file_name)
    flow_file:updateAttribute('filename', new_file_name)
    session:transfer(flow_file, REL_SUCCESS)
    log:info('rename_file success')
  else
    log:info('no work to do')
  end
end

Log output showing the error:
