Possible bug caused by bson ObjectIds?

[bnic]

The connector inserts one document then barfs. I tried pyelasticsearch to manually populate and received the same error until I cast the ObjectId into a string.

Traceback (most recent call last):

I'm going to close this issue- I could not reproduce it. I think this was caused by a bug in the way that ObjectIDs, DBRefs, etc were being encoded that was just fixed in the latest commit. If this is still an issue, please reopen the issue.
