   ### What happened
   
   below is my seatunnel job config:
   env {
       execution.parallelism = 1
   }
   
   source {
     mongodb {
      uri = "mongodb://xxxxxx:xxx@xxxx:27017"
      database = "order_center"
      collection = "vehicleOrderOperation"
      flat.sync-string=true
      schema {
        fields {
              _id = string
        }
      }
      match.query="{ createTime : { $gte : ISODate(\"${pardate}T00:00:00Z\"), 
$lte : ISODate(\"${nowdate}T23:59:59Z\") } }"
   }
   }
   transform {
       #sql {
       #    sql = "select name,age from fake"
       #}
   }
   
   sink {
       #Console {}
       
     S3File {
       bucket = "s3a://mhero-bdp-prod"
       tmp_path = "/tmp/seatunnel/mongo/vehicleOrderOperation"
       path="/xxxxxx_tmp/t_ods_vehicle_order_operation"
       fs.s3a.endpoint="http://xxxx:xxx";
       
fs.s3a.aws.credentials.provider="org.apache.hadoop.fs.s3a.SimpleAWSCredentialsProvider"
       access_key = "xxx"
       secret_key = "xxx"
       #file_format_type = "orc"
     }
   
   }
