Я пытаюсь запустить автономный Debezium с исходящим SMT, используя настраиваемый столбец полезной нагрузки (after
) и дополнительный столбец jsonb
(before
), но задача выдает ошибку:

Мне кажется, что debezium пытается получить столбец payload
из моей таблицы campaigns.outbox
, хотя я явно переопределяю столбец полезной нагрузки transforms
в моих рабочих параметрах (./config/connect-campaigns-outbox.properties
):

Минимальная схема PG, необходимая для воспроизведения ошибки:
CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
CREATE TYPE campaigns.outbox_event_type AS ENUM (
'campaign',
'creative'
);
CREATE TABLE campaigns.outbox (
id UUID PRIMARY KEY,
type campaigns.outbox_event_type NOT NULL,
aggregate_id TEXT NOT NULL,
before JSONB,
after JSONB
);
Воспроизвести ошибку:
insert into campaigns.outbox (id, type, aggregate_id, before, after) values (uuid_generate_v4(), 'campaign', '1', NULL, '{"id":1,"title":"teste","description":"teste description"}');
Я делаю что-то не так или я должен сообщить об этом как о проблеме команде Jboss?
