### Search before asking - [x] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened When I use the sql below in my influx source: `sql = "SELECT tagName,value,time FROM history_value where time >= '2025-01-01' and time < '2025-01-02'"` It throws exception below: `Exception in thread "main" org.apache.seatunnel.core.starter.exception.CommandExecuteException: SeaTunnel job executed failed at org.apache.seatunnel.core.starter.seatunnel.command.ClientExecuteCommand.execute(ClientExecuteCommand.java:228) at org.apache.seatunnel.core.starter.SeaTunnel.run(SeaTunnel.java:40) at org.apache.seatunnel.core.starter.seatunnel.SeaTunnelClient.main(SeaTunnelClient.java:34) Caused by: org.apache.seatunnel.connectors.seatunnel.influxdb.exception.InfluxdbConnectorException: ErrorCode:[API-01], ErrorDescription:[Configuration item validate failed] -
