Apache kafka 如何解决debezium mongo db源连接器中的java.lang.NullPointerException？

我正在使用debezium mongo DB源连接器。它对于创建/更新很有效，但是对于删除，我希望在目标数据库中过滤完整的文档。为此，我将连接器配置为处理模式

"transforms.unwrap.delete.handling.mode" : "rewrite",

但它给出了错误（附屏幕截图）

虽然我这样做的时候效果很好

"transforms.unwrap.delete.handling.mode" : "drop",

但在这种情况下，我得到的值为null

我尝试了下面的transforms.unwrap.type，但得到了相同的结果

“transforms.unwrap.type”：“io.debezium.transforms.UnwrapFromEnvelope”

“transforms.unwrap.type”：“io.debezium.connector.mongodb.transforms.UnwrapFromMongodBenDevelope”

“transforms.unwrap.type”：“io.debezium.transforms.ExtractNewRecordState”

在删除为空的情况下，是否有办法获得完整的文档

请查看随附的错误截图和连接器的完整配置
