我正在使用Kafka源JDBC连接器来拉取数据库事件，并且我正在独立模式下运行kafka连接。当我运行此文件时，我收到显示的错误。请帮助我。
法典：
name=sailpointdb01107
connector.class=io.confluent.connect.jdbc.JdbcSourceConnector
tasks.max=1
connection.password = xxxxx
connection.url = jdbc:oracle:thin:@xxxxx:1521/xxxxx
connection.user =xxxxx
query= SELECT * FROM (SELECT NAME, TO_TIMESTAMP('19700101', 'YYYYMMDD')+ NUMTODSINTERVAL(COMPLETED/1000,'SECOND') AS TASKFAILEDON FROM task WHERE COMPLETION_STATUS='Error')
mode= timestamp
timestamp.column.name=TASKFAILEDON
topic.prefix=testing
validate.non.null=false
transforms=TimestampConverter
transforms.TimestampConverter.type=org.apache.kafka.connect.transforms.TimestampConverter$Value
transforms.TimestampConverter.format=yyyy-MM-dd
transforms.TimestampConverter.target.type=Timestamp
transforms.TimestampConverter.target.field=TASKFAILEDON
错误：

在连接器上配置的此行可以避免此问题。
