SolrCloud No Active Slice

[James Webster]

I'm having a config issue, I'm posting the error from Solrj which also
includes the cluster state JSON:

 org.apache.solr.common.SolrException: No active slice servicing hash code

All nodes are active in the solr admin, not sure where to go from here.

Thanks in advance!
