Hi Peter,

Just came to know that this issue is coming when the same node index is
queried before the previous iterator is closed.
Can you check from that angle and let us know if that is the actual issue.

Also, can you let us know when the REST API impl over blueprints 2.1 would
be committed.

Thanks in Advance..
