I have log format like this

```auto
<<<\n
Accept:application/json, text/javascript, */*; q=0.01\r\n
Content-Type:application/x-www-form-urlencoded; charset=UTF-8\r\n
Origin:https://discuss.elastic.co\r\n
Referer:https://discuss.elastic.co/c/logstash\r\n
\r\n
<soap><a><b></b></a></soap>
>>>\n

```

and my logstash.conf

```auto
input {
    s3 {
        codec => multiline {
             pattern => "<<<\n"
             negate => true
             what => "previous"
        }
    }
}

output {
    elasticsearch {
        host => "192.168.99.100:9200"
        index => "tt"
    }
}

```

With this config, I always lose last one log.  
for example, I have 450 logs but only 449 logs in Elasticsearch.

How could I solve this problem ?  
Or I should not use multiline codec ?

English is not my mother language, if any word is offensive, please tell me.

Thank you
