[GitHub] [druid] jamiechapmanbrn opened a new issue #11499: Druid get lookup for individual lookup failing with 500
jamiechapmanbrn opened a new issue #11499:
URL: https://github.com/apache/druid/issues/11499
When getting details about a specific lookup as documented in https://druid.apache.org/docs/latest/querying/lookups.html#get-lookup-1, I get a 500 error with the following stack trace instead of a json response.
### Affected Version
druid 21.1
java 11
Example:
```
curl -L http://localhost:8083/druid/listen/v1/lookups

FrankChen021 commented on issue #11499:
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)`
