Dear all, I would like to change my actual flow:  
FROM  
metricbeat \> elasticsearch  
TO  
metricbeat \> logstash \> elasticsearch

The following configuration works on my laptop but not on a linux production machine 😕 ; any idea on the root cause of this problem?

I received this kind of error: (see below for the complete error message)  
`logstash Encountered an unexpected error submitting a bulk request! undefined method sanitized`

Thanks in advance for you help.

kr,  
O.

Here is my actual setup:

```
# logstash config for beats flow:
input {
  beats {
    port => 5044
  }
}
 
filter {
}
 
output {
  elasticsearch {
    hosts => ["laod.balancer.url:80"]
    index => "%{[@metadata][beat]}-%{+YYYY.w}"
    document_type => "%{[@metadata][type]}"
    user => "logstash_internal"
    password => "xxxx"
  }
}

```

# test configuration file : OK

```
[root@server01 conf.d]# /usr/share/logstash/bin/logstash "--path.data" /${MY_PATH}/data/logstash-elk-beats "--path.logs" /${MY_PATH}/logs/elk-beats "--log.level" "error" "--path.config" /${MY_PATH}/config/conf.d/logstash-elk-beats.conf --config.test_and_exit
Sending Logstash's logs to /${MY_PATH}/logs/elk-beats which is now configured via log4j2.properties
Configuration OK

```

# check des logs: NOK

```
[root@server01 conf.d]# tail -100f /${MY_PATH}/logs/elk-beats/logstash-plain.log

I'm encountering the same issue. It appears to have been introduced today in Logstash 5.6.3. I am running Logstash in a Docker container.
