-------------------------------------------
>From version 5.4.0 of Confluent Schema Registry we have [GET
>/schemas/ids/\{int:
>id}/versions|https://docs.confluent.io/5.4.0/schema-registry/develop/api.html#get--schemas-ids-int-%20id-versions]
> call so we can optimize work if Cofluent Version above 5.4.0. But still cant
>understand why this error can be produced in this scenario.
> AvroReader controller can't get confluent schema IDs except only the latest
