使用REST连接时报错user is required

[XieRW]

connect.log日志如下：

java.sql.SQLException: ERROR (0x2319): user is required

sink-demo.json:

{
  "name": "TDengineSinkConnector",
  "config": {
    "connector.class":"com.taosdata.kafka.connect.sink.TDengineSinkConnector",
    "tasks.max": "1",
    "topics": "meters",
    "connection.url": "jdbc:TAOS-RS://127.0.0.1:6041",
    "connection.user": "root",
    "connection.password": "taosdata",
    "connection.database": "power",
    "db.schemaless": "line",
    "data.precision": "ns",
    "key.converter": "org.apache.kafka.connect.storage.StringConverter",
    "value.converter": "org.apache.kafka.connect.storage.StringConverter",
    "errors.tolerance": "all",
    "errors.deadletterqueue.topic.name": "dead_letter_topic",
    "errors.deadletterqueue.topic.replication.factor": 1
  }
}

我将sink-demo.json其中的"connection.url": "jdbc:TAOS://127.0.0.1:6030"修改为"connection.url": "jdbc:TAOS-RS://127.0.0.1:6041?user=root&password=taosdata"就不会再出现问题了，怀疑是改成REST连接后，connection.user配置项不生效，只好在url上直接拼接了。

希望能验证这个问题并修复。

用restful方式，将参数写在链接里之后消费kafka消息写入数据的时候会报args error 吗？

我也是用restful方式,然后提示找不到table name
