Ksqldb create stream error while using oneof protobuf on schema registry - apache-kafka

Question

I'm having an issue while trying to create a stream with a topic that has a defined protobuf schema that uses oneof clause, I try to create the stream referring to the VALUE_SCHEMA_ID of the created schema on schema registry, the idea of this stream is that it transforms some data into one of the objects accepted on the oneof protobuf definition but an error is being thrown, here are the files:
Protobuf schema:
syntax = "proto3";
import "google/protobuf/timestamp.proto";
message SettlementContextEvent{
string type = 1;
oneof event_data {
SettlementContextCreatedEvent settlement_context_created = 2;
MovementsCalculatedEvent movements_calculated = 3;
}
message SettlementContextCreatedEvent{
string status = 1;
string type = 2;
int32 account_id = 3;
string transaction_id = 4;
int64 order_id = 5;
google.protobuf.Timestamp creation_date = 6;
string additional_information = 7;
}
message MovementsCalculatedEvent{
repeated Movement movements = 1;
}
message Movement{
string id = 1;
...
}
}
This schema is under settlement_context_events-value subject with id 73
This is the Ksql query:
CREATE
STREAM IF NOT EXISTS SETTLEMENT_CONTEXT_CREATION_TRANSFORMER
WITH (KAFKA_TOPIC = 'settlement_context_events',
PARTITIONS = 10,
REPLICAS = 1 ,
VALUE_FORMAT = 'PROTOBUF',
VALUE_SCHEMA_ID= 73)
AS
SELECT var0 as `aggregate_id`,
Struct(`settlement_context_created` := Struct(
`status` := var1,
`type` := var2,
`account_id` := var3,
`tansaction_id` := var4,
`order_id` := CAST(var5 AS BIGINT),
`creation_date` := var6,
`additional_information` := var7
) ) AS `event_data`,
'test' AS `type`
FROM SETTLEMENT_CONTEXT_CDC PARTITION BY var0;
As you see it es using the settlement_context_createdobject defined in the oneof clause, but I'm getting the following error:
The following value columns are changed, missing or reordered: [`event_data` STRUCT<`settlement_context_created` STRUCT<`status` STRING, `type` STRING, `account_id` INTEGER, `tansaction_id` STRING, `order_id` BIGINT, `creation_date` TIMESTAMP, `additional_information` STRING>>]. Schema from schema registry is [`event_data_0` STRUCT<`settlement_context_created` STRUCT<`status` STRING, `type` STRING, `account_id` INTEGER, `transaction_id` STRING, `order_id` BIGINT, `creation_date` TIMESTAMP, `additional_information` STRING>, `movements_calculated` STRUCT<`movements` ARRAY<STRUCT<`id` STRING, `account_id` INTEGER, `operation` STRING, `value` DOUBLE, `creation_date` TIMESTAMP, `description` STRING, `previous_balance` DOUBLE, `billable` BOOLEAN, `document` STRING, `parent_account_operation_id` STRING, `released` BOOLEAN, `previous_reserve_balance` DOUBLE, `previous_frozen_balance` DOUBLE, `movement_type` STRING, `document_support_type` STRING, `release_date_of_reserve_fund` TIMESTAMP, `related_transaction_id` STRING, `accreditation_order` INTEGER>>>>, `type` STRING]
NOTE: I also tried changing the event_datastruct name to event_data_0 but got no luck does anyone knows why Ksqldb adds this 0 at the end?
