MikeThomsen commented on issue #3318: NiFi-5537 Add Cypher Bundle URL: https://github.com/apache/nifi/pull/3318#issuecomment-503797146 > It routes the flow file to failure because it can't deserialize the "result", which I assume is because there's no real result at all. I don't think that's the case here. The Gremlin graph traversal object is a little tricky in that respect when combined with the rest of the scripting process there. AFAIK, it will create the objects on the current transaction until something triggers a rollback. In that case, I think the inability to serialize and send back to the client counts as such an event. `.property()` is a traversal step, and you have to use calls like `id()` and `label()` or maybe `valueMap().next()` to get something that can be reliably serialized and sent back to the client. I'll write some additional documentation to try to clarify things a little (caveat being I'm the near-sighted one eyed man in the kingdom of the blind on that front with our users!)
