Filebeat + logstash infinite loop

Hello.
I am new to elasticsearch and I am trying to send json data with filebeat to logstash -> elasticsearch.

#filebeat.yml
filebeat.inputs:
- type: log
  enabled: true
  paths:
    - /var/log/json-data2.log
  json.message_key: log
output.logstash:
   hosts: ["localhost:5044"]
#logstash.conf
input {
        beats {
                port => 5044
                codec => json
        }
}

filter {
        json {
                source => "message"
         }
        mutate {
                remove_field => ["message"]
        }
}

output {
        elasticsearch {
                hosts => "http://localhost:9200"
                index => "demo-index5"
        }

        stdout {}
}
#json-data2.log

I get an endless loop of:

When i send json file without filebeat through logstash, it works like a charm, but with filebeat I just cant get it to work.
