I haven't seen this error before but there is some crazy JavaScript in the example/files update processing. If you're indexing CSV where each row is a separate document, example/files may not be the config you want to start with anyway. Try creating your collection without that -d.
Oh, I see the issue - example/files script looks for a "content" field (to extract email addresses and URLs from) and there isn't one (see "null" below). Again, example/files isn't designed for non-"content" documents. I'll make a note to fix this issue (by ignoring the extraction part when no content) though.
