Description

spinning off of SOLR-9377...

the [subquery] transformer doesn't do anything to explicitly request the document fields it needs in order to construct the subquery it executes (ie every field foo to fill in $row.foo)). Which can lead to unexpected errors when parsing/executing the subquery.

The workaround is to only use the [subquery] transformer in conjunction with an fl=* glob, or explicitly list all fields needed.
