I guess the problem appeared since we added a new node and installed 6.3.x version of filebeat.  
Yesterday I upgraded all the filebeats in the infrastructure, but the problem is still there.

I found a topic of [Problem with transfer Filebeat 6.1.3 \> Logstash 6.1.3 \> Elasticsearch 6.1.3](https://discuss.elastic.co/t/problem-with-transfer-filebeat-6-1-3-logstash-6-1-3-elasticsearch-6-1-3/136264/5). There they recommend to mutate the fields in order to pass into the new index schema.
