the Logs app in Kibana expects the log documents to adhere to the ECS schema. In this case that means that it expects the timestamp to be in the @timestamp field and the message to be in message.
Hi @weltenwort thanks for your answer,
You are right! My problem was that I was changing "message" field to "message_log", so really "message" field didn't exist.
I have changed in Kibana Logs the "Log Columns" to add "message_logs" and it works now!
