我正在使用生成如下模式的 Avro 值转换（这只是一个子集，因为它很大）

当我运行以下命令以创建一个流时
CREATE STREAM stream_invtr_t_json WITH (KAFKA_TOPIC='InvTR_T', VALUE_FORMAT='AVRO');
然后我描述了那个流，模式是一种非常奇怪的格式。我想使用 KSQL 来过滤掉特定信息并适当地分散这些事件。但是我无法从 Kafka Topic => KSQL Stream => Kafka Topic => Sink 出发。如果然后我从该流中创建一个新主题，并尝试将其消化到我得到的接收器中
Expected Envelope for transformation, passing it unchanged
然后是关于 PK 丢失的错误。我试图删除展开转换只是为了看看它会如何出现并收到错误。
