Facing error while using jsonb datatype while using Yugabyte as the persistent store for Janusgraph

Getting this error on gremlin console while running command “bin/yugabyted start” on yugabyte terminal
I’m using yugabyte as a storage backend with janusgraph as a middleware to connect it with gremlin server.

Hi @ankitch

Welcome to YugabyteDB Forum!
Are you using our fork of the driver https://github.com/yugabyte/cassandra-java-driver ? We have added jsonb support there.

Thank you for the response, no we are not using the fork of the driver, we will use and update here
