I have a cluster with 4 nodes running dse. If I try to make a call to the TermsComponentHandler on one of the nodes, I am required to specify the other shards as well according to http://wiki.apache.org/solr/TermsComponent.
But if I do specify the other shards, I receive a NullPointerException as follows:

Does anyone have an idea what may be causing this? And how to fix it?
This is the call I make:
