No serializer found for class io.druid.client.ImmutableDruidDataSource

[JeKuOrdina]

Problem

I've seem to have misconfigured the druid installation and cannot retrieve the full metadata for datasources.

Get request error for http://<host>:8081/druid/coordinator/v1/datasources/wikiticker?full=true

 com.fasterxml.jackson.databind.JsonMappingException: No serializer found for class io.druid.client.ImmutableDruidDataSource and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) )

Any pointers on where I should look to resolve this issue ?

@JeKuOrdina, thank you for the reporting! This was introduced in #5054. I'll reopen this issue.
