Hi,

I am running a Clickhouse cluster on k8s and reading from Kafka topics. I am using Clickhouse 20.4.4 .18 and the 0.9.9 version of the Clickhouse operator.  The topics are in AvroConfluent format and everything worked well until I started having an exception for on eof the topics where the complaint is :"Invalid name space"
The name of namespace is something like xxx-yyyy.prod. 

Do you have any idea what this can be about? 
Many thanks!
catch (const avro::Exception & e)
            {
                throw Exception(e.what(), ErrorCodes::INCORRECT_DATA);
            }
        }
        catch (Exception & e)
        {
            e.addMessage("while fetching schema id = " + std::to_string(id));
            throw;
        }
    }
    Poco::URI base_url;
    LRUCache<uint32_t, avro::ValidSchema> schema_cache;
};

    const auto & base_url = format_settings.avro.schema_registry_url;
