Kafka jdbc sink connect上的模式异常

我试图使用Kafka jdbc sink connect将行插入到我的Oracle表中 . 我在我的Kafka主题（JSON）中有消息，如下所示;

[{"f1":"qws","f2":"zcz","f3":"SDFF","f4":"f33bfed577bcd7c4625479bd3cd13323--1132061303","f5":null,"f6":null,"f7":"ghSDAgh/akdjytfd/jhsgd","f8":"hsfgd/sdfjghsfjd/jsg","f9":null,"f10":"ASD","f11":"sdfg/vbnm","f12":"S","startTime":"2018-01-30T05:24:41.162","_startTime":"DATE","f13":219,"f14":"http://192.168.0.1:1234/asd/fgh/jkl/zxc/vbn/qwe/rty","f15":"fe80:0:0:0:7501:14d9:b44b:2a95%eth5","f16":1234,"f17":"ABCD-1234","f18":"192.168.0.1","f19":"sdfgd","dfgVO":{"fa1":null,"fa2":"formats","fa3":""qwe.rty.uiop.asd.fgh.jkl.zxc.vbn.asdf@61e97f29"","fa4":7,"fa5":79,"fa6":null,"fa7":"{}","fa8":1517289881381},"f20":null,"f21":"http-drte-1234-uik-7","f22":false,"f23":false,"f24":false}]

我有如下连接器配置;

name=jdbc-sink-2
connector.class=io.confluent.connect.jdbc.JdbcSinkConnector
tasks.max=1
topics=my_topic_1
connection.url=jdbc:oracle:thin:@192.168.0.1:1521:user01
connection.user=USER1
connection.password=PASSWD1
auto.create=true
table.name.format=MY_TABLE_2
key.converter=org.apache.kafka.connect.json.JsonConverter
value.converter=org.apache.kafka.connect.json.JsonConverter
producer.retries=1

当我启动连接器时，我收到以下错误;

[2018-01-30 11:16:55,417] ERROR Task jdbc-sink-2 threw an uncaught and unrecoverable exception (org.apache.kafka.connect.runtime.WorkerTask:148)
org.apache.kafka.connect.errors.DataException: JsonConverter with schemas.enable requires "schema" and "payload" fields and may not contain additional fields. If you are trying to deserialize plain JSON data, set schemas.enable=false in your converter configuration.

然后我将以下配置添加到现有的连接器配置中;

key.converter.schemas.enable=false
value.converter.schemas.enable=false

现在，我收到另一个错误如下;

这表示我需要像键值模式格式一样修改我的Kafka消息 . 我无法修改我的Kafka消息格式，因为它是由其他人发布的 . 我该如何解决这个错误？

谢谢 .
