We see the following warning in logstash logs
[2022-06-27T12:23:27,848][WARN ][deprecation.logstash.codecs.json][my_pipeline] Relying on default value of pipeline.ecs_compatibility, which may change in a future major release of Logstash. To avoid unexpected changes when upgrading Logstash, please explicitly declare your desired ECS Compatibility mode.
We found the following thread and set the ecs_compatibility = disabled at pipeline level
[Warning 'Relying on default value of `pipeline.ecs_compatibility' after updating to logstash 7.16.1](https://Warning ‘Relying on default value of `pipeline.ecs_compatibility’)
The number of warnings reduced but we still see some warnings. Any idea what we are missing?
Additionally, we see the following error, it seems it tries to look for 2x.json template and that does not exist. Do we need to install something special?
