Draco NGSIToCassandra processor giving error

I am trying to persist data coming from Orion Context Broker to Cassandra by using ging/fiware-draco dockerhub image.

The moment I drag and drop the NGSIToCassandraError it throws an error as shown in the image. I tried the older versions of docker image with no help. Older versions like 1.3.1 or 1.3.4 does not throw this error, but they have their own bugs. None works as stable as NGSIToPostgreSQL.

My question is: Is NGSIToCassandra used in production at all? Should i try to use Cygnus -> Kafka -> Cassandra approach? Any help is appreciated.
