  <p>[2022-05-28 19:25:09,454] ERROR [nginx-tdengine|task-0] WorkerSinkTask{id=nginx-tdengine-0} RetriableException from SinkTask: (org.apache. kafka.connect.runtime.WorkerSinkTask:600)
  RetriableException: java.sql.SQLException: Exception chain:
  SQLException: TDengine ERROR (80000221): Invalid JSON format</p>
  <p>The TDengine version is 2.4.0.14</p>
  <p>We refer to the documentation at <a href="https://docs.taosdata.com/third-party/kafka" rel="nofollow noreferrer">https://docs.taosdata.com/third-party/kafka</a>.
