Decimals are being shown as array of bytes in Preview
Screenshot of preview attached.
Decimal types are shown as byte array in preview e.g. 0 is shown as 
StructuredRecordConvertor.toJsonString() as does the same.
When decimals are shown to user, they should be readable.
Preview shows logical types in iso format
There are 2 options for displaying logical types in preview:
1.) Make backend change to support correct serialization and deserialization of structured records with logical types. :
After this change, list of JsonElement returned from store would contain string values for logical types instead of corresponding primitive types. This means returned serialized structured record fields with logical type will not comply with the schema.
2.) Make the changes in UI and have an open Jira to apply right fix in backend.
The proposed backend fix is an api response change. Considering this Jira is tied to the patch version, it would be good to explore if this can be fixed in UI.
This has been committed for 6.1.4. For any changes please confirm with .
