How do I solve this. Logstash is working but the message is repeating all the time

[deprecation.logstash.codecs.plain] Relying on default value of pipeline.ecs\_compatibility, which may change in a future maj or release of Logstash. To avoid unexpected changes when upgrading Logstash, please explicitly declare your desired ECS Compatibility mode.

You need to explicitly set the value for `pipeline.ecs_compatibility`.

> **To avoid unexpected changes when upgrading Logstash, please explicitly declare your desired ECS Compatibility mode.**

You can set it per pipeline in the `pipelines.yml` file or globally in the `logstash.yml` file.

Here is the [documentation](https://www.elastic.co/guide/en/logstash/8.2/ecs-ls.html#ecs-configuration-pipeline) on how to configure it.
