flavor8 on ""Error creating document" when using Solr's DataImportHandler - NPE in CassandraDirec"

Hello,

I am using solr's DataImportHandler to import into a solr core running in DSE. Unfortunately I'm getting an NPE when the SolrWriter submits the document to Cassandra; I don't have the source for DSE, so I'm not sure what's happening. Here's the stacktrace; does it indicate anything that yield a diagnosis?

Thanks
