[GitHub] [druid] FrankChen021 commented on issue #11499: Druid get lookup for individual lookup failing with 500

URL: https://github.com/apache/druid/issues/11499#issuecomment-889591041


   This is a bug. The code here returns an object of type of `java.util.Optional` which can't be serialized.
   
   https://github.com/apache/druid/blob/59e61e127a14ff4dd41e76a2ff1bfd90ea3ac8af/server/src/main/java/org/apache/druid/query/lookup/LookupListeningResource.java#L113
   
   It should be fixed as `manager.get(id).orElse(null)`
