> When running a group query with group sort, and passing 'score' field in fl list, I am getting the following exception.
> Sample Query which is failing : [http://localhost:8983/solr/collection1/select?fl=field1,score&group.query=field2:(]"ABC")&q=*:*&group.sort=field3+desc&group=true&_route_=shard1
> Removing score from fl fixes the error.
