Solution:

Head to SOLR admin page – http://127.0.0.1:8983/solr, and refresh index that’s throwing an error exception; so in my case genericsearch_master_index.

reload_solr_index

Test again, it should work now.

rebuilding_index_using_indexing_manager

 

Update 14.08.2016 : If the above steps failed. Double check the schema, and see if it’s the latest version and/or has the right settings on it.
