    Root Cause Analysis

    1. org.neo4j.kernel.api.exceptions.ProcedureException

      Procedures must return a Stream of records, where a record is a concrete class that you define, with public non-final fields defining the fields in the record. If you''d like your procedure to return `Stream`, you could define a record class like: public class Output '{' public Stream out; '}' And then define your procedure as returning `Stream<Output>`.
