That is a client side error message meaning that the statement couldn't be
handled. There should be better error handling around this, but its not in
place currently.

And on Solr side, the logs seem okay:


The logs you shared don't seem to be the full logs. There will be a related
exception on the Solr server side. The exception on the Solr server side
will explain the cause of the problem.
