I'm trying to understand what is wrong with my query or collection. I have a functioning solr schema and collection. I'm running Solr 7.2
When I run with a facet.field it works, but if I change it to use a json.facet it throws a class cast exception. json.facet=prod:{type:terms,field:product,mincount:1,limit:8} java.lang.String cannot be cast to java.util.Map The product field is defined as <field name="product" type="lowercase" indexed="true" stored="true" /> And lowercase is defined as: <fieldType name="lowercase" class="solr.TextField" positionIncrementGap="100"> <analyzer> <tokenizer class="solr.KeywordTokenizerFactory"/> <filter class="solr.LowerCaseFilterFactory" /> </analyzer> </fieldType> I don't have enough information to understand what its complaining about.
