I am running Solr 5.5.4. When I open the index manager, I see a bunch of errors in the Sitecore log file of the following:
5664 13:40:46 ERROR Object reference not set to an instance of an object. Source: Sitecore.ContentSearch.SolrProvider at Sitecore.ContentSearch.SolrProvider.SolrIndexSummary.get_NumberOfDocuments() at Sitecore.ContentSearch.Client.Forms.IndexingManagerWizard.BuildIndexCheckbox(String name, String header, ListString selected, ListString indexMap)
Our Solr solution is using zookeeper and a Solr Cloud setup. Does anyone know why that command isn't working?
