How to send data from HTTP input to ElasticSearch using Logstash and jdbc_streaming filter?

Elastic Stack Logstash
1

I want to send data from Http to elasticsearch using logstash and I want to enrich my data using jdbc_streaming filter plugin. This is my logstash config:

input {
  http {
    id => "sensor_data_http_input"
    user => "sensor_data"
    password => "sensor_data"
  }
}

filter {
  jdbc_streaming {
    jdbc_driver_library => "E:\ElasticStack\Logstash\logstash-7.4.1\logstash-core\lib\jars\connector_6.jar"
    jdbc_driver_class => "com.mysql.cj.jdbc.Driver"
    jdbc_connection_string => "jdbc:mysql://localhost:3306/sensor_metadata"
    jdbc_user => "elastic"
    jdbc_password => "hide"
    statement => "select st.sensor_type as sensorType, l.customer as customer, l.department as department, l.building_name as buildingName, l.room as room, l.floor as floor, l.location_on_floor as locationOnFloor, l.latitude, l.longitude from sensors s inner join sensor_type st on s.sensor_type_id=st.sensor_type_id inner join location l on s.location_id=l.location_id where s.sensor_id= :sensor_identifier"
    parameters => { "sensor_identifier" => "sensor_id"}
    target => lookupResult
  }

  mutate {
    rename => {"[lookupResult][0][sensorType]" => "sensorType"}
    rename => {"[lookupResult][0][customer]" => "customer"}
    rename => {"[lookupResult][0][department]" => "department"}
    rename => {"[lookupResult][0][buildingName]" => "buildingName"}
    rename => {"[lookupResult][0][room]" => "room"}
    rename => {"[lookupResult][0][floor]" => "floor"}
    rename => {"[lookupResult][0][locationOnFloor]" => "locationOnFloor"}
    add_field => {
      "location" => "%{lookupResult[0]latitude},%{lookupResult[0]longitude}"
    }
    remove_field => ["lookupResult", "headers", "host"]
  }

}

output {
  elasticsearch {
    hosts => ["localhost:9200"]
    index => "sensor_data-%{+YYYY.MM.dd}"
    user => "elastic"
    password => "hide"
  }
}

But when I start logstash, I see following error:

I am enriching my http input with some data in my mysql database but it doesn't start logstash at all. every thing is latest version :slight_smile:
