Debezium 发件箱模式属性 transforms.outbox.table.expand.json.payload 删除空数组

Question

我正在使用 debezium postgres 连接器实现发件箱模式，建立在官方文档的基础上：https://debezium.io/documentation/reference/stable/transformations/outbox-event-router.html.

Evething 好，但现在我看到奇怪的行为，如果 kafka 消息中缺少空数组

transforms.outbox.table.expand.json.payload 

真正的

如果在表中我有值“{“some”：“test”，“agreemets”：[]}”在主题消息中看起来{“some”：“test”}。

第一行，如果我们设置为 false 第二行，如果我们设置为 true

如何防止删除空数组？

我完整的 Kafka 连接配置
