Hi all,

So yesterday we installed logstash and Elasticsearch via yum from repo:  
`name=Elasticsearch repository for 7.x packages baseurl=https://artifacts.elastic.co/packages/oss-7.x`  
(forgive me if a misuse terms, I am a software developer, not a systems engineer) on a linux server.

Installed versions:

```auto

```

```auto

```

Elastic is up and running:

```auto
curl "localhost:9200"
{
  "name" : "wntstfo03.izaaksuite.nl",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "wRQY0SfoTCuo5MtnxtJ_FA",
  "version" : {
    "number" : "7.10.2",
    "build_flavor" : "oss",
    "build_type" : "rpm",
    "build_hash" : "747e1cc71def077253878a59143c1f785afa92b9",
    "build_date" : "2021-01-13T00:42:12.435326Z",
    "build_snapshot" : false,
    "lucene_version" : "8.7.0",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"

```

But when starting logstash with following configuration:

```auto
input {
    jdbc {
        jdbc_connection_string => "jdbc:oracle:thin:@wntstdb03.izaaksuite.nl:1521:wntstf2"
        jdbc_user => "webnext_zaken"
		jdbc_password => "webnext_zaken"
        jdbc_driver_library => ""
        jdbc_driver_class => "Java::oracle.jdbc.driver.OracleDriver"
        statement_filepath =>"/appl/sw/webnext/logstash/config_documenten/queries/documenten.sql"
	last_run_metadata_path => "/appl/sw/webnext/logstash/config_documenten/parameters/.jdbc_last_run_doc"
    }
}

# The filter part of this file is commented out to indicate that it is
# optional.

#filter {
#    
#}

output {
 stdout { codec => rubydebug }
  file { 
  path => ["/appl/sw/webnext/logstash/config_documenten/output/documenten.txt"]
 	}
  elasticsearch { 
 		hosts => ["localhost:9200"]
 		index => "documenten"
 		document_id => "%{zaakdoc_id}"
 	}
}

```

we get an error:

If you need to run Elasticsearch 7.10 then downgrade your logstash to 7.10.
