["Joel Bernstein (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-9128?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15289137#comment-15289137 ] 

Joel Bernstein commented on SOLR-9128:
--------------------------------------

Ran across a few more issues while fixing error handling issues. So I'll bundle those fixes into this ticket as well:

FacetStream: was throwing NPE with zero facet results. TODO: add a test case for this. This effects the SQLHandler operating in facet aggregationMode.

GatherNodesStream: explain was breaking on the admin stream console, due to issues with toExpression.

CloudSolrStream: was throwing NPE on missing params rather then throwing proper exception. TODOL add test case for this.

GraphHandler: did not have the SelectStream registered.
