Hi.
I am sending a log (from a kannel instance) through filebeat to logstash and then to elastic search cluster.
All components are in the latest version (6.0.0) and I am getting the error "Content-type header [application/x-ndjson; charset=UTF-8] is not supported" in Kibana when I click in discover or even try to create a graphic in visualize.
The kibana has discovered all the fields in the created Index.
It is true that the messages have some UTF-8 (latin with accents) characters.
I haven't installed X-Pack. All of the components were installed with rpm in a CentOS environment.
Can you tell me what could the error be?
Regards
Ricardo
