Hi friends, please your help, we have this message: in log from logstash

```auto
[2023-04-14T20:49:18,951][INFO][logstash.outputs.elasticsearch][rpa_centria_test] Failed to perform request {:message=>"PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target", :exception=>Manticore::ClientProtocolException, :cause=>#<Java::JavaxNetSsl::SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target>}

```

My .conf is:

```auto
input {
  pipeline { address => rpa_centria_test }
}

filter {
   csv {
        separator => ","
        columns => ["fecha","robot","nom_proceso","id_proceso","id_item","componente","aplicacion","paso","tipo","nivel","accion","mensaje","estado"]
   }

        mutate {
                remove_field => ["message","tags"]
        }

}

output {
     elasticsearch {
      hosts => ["https://192.168.0.101:9200"]
      index => "rpa_centria_405123_contabilidad"
      api_key => "SnZ6ZGZJY0IzMjJ0M3hscFpkUjc6RGQ4SFZLakZRZzJPcnNmNEVWcn"
      action => "create"
      ssl => true
   }
}

The error you are seeing is about certificates. You are trying to reach an `https` endpoint and using `ssl => true` so it's looking for a [cacert setting](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-cacert) to know where the path of the certificate is. You could try to set the [SSL Verification](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-ssl_certificate_verification) to false and see if it connects, but in order to fully utilize the security option it needs a certificate.
