This is good. What we are NOT seeing is the contents of the metadata changing while going to-and-from your precommit hook. I think you need to be concerned about a few issues when using JS precommit hooks:
1) Your data must never contain a character that is not encoded in UTF-8. Yours looks like ASCII/Latin-1 so that should be fine. 2) Large objects will take a while to transfer to and from the JS VM because it has to be marshalled in each direction, which could be the source of a timeout. Those things said, it would be good to get more information on what the exact error was as reported by Riak. Do you have riak logs or transcripts of client sessions?
