Hi, problem should be caused by missing surrounding curly brackets.
That is, your query is
json.facet=prod:{type:terms,field:product,mincount:1,limit:8}
instead it should be
json.facet=*{*prod:{type:terms,field:product,mincount:1,limit:8}*}*
that causes the wrong interpretation of the "json/facet" parameter
(String instead of Map)
Cheers,
Andrea

Hello, Webster.
Have you managed to capture stacktrace?

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.
Thanks
