Getting class_cast_exception when trying to use profile:true with sltr query

[ayushKataria]

When I try to run a query where there is a must or should clause in the query and in rescore I have an sltr query with my model, I get the below error

class org.elasticsearch.search.profile.query.ProfileScorer cannot be cast to class com.o19s.es.explore.PostingsExplorerQuery$PostingsExplorerScorer (org.elasticsearch.search.profile.query.ProfileScorer is in unnamed module of loader 'app'; com.o19s.es.explore.PostingsExplorerQuery$PostingsExplorerScorer is in unnamed module of loader java.net.FactoryURLClassLoader @55d99dc3)

Can someone help with this?

Can you give details on which JVM you're seeing this on?

@sstults still seeing this issue (taking over the debugging from @blackmad ), let me know what information I can provide to help you reproduce!

@jiahuijiang , I'm sorry but I'm not going to be able to follow up on this anytime soon. Elastic has announced their adoption of LTR into Elasticsearch itself, and I'm working on the OpenSearch LTR plugin.
