See [this](https://discuss.elastic.co/t/problem-logstash-outputs-elasticsearch-could-not-index-event-to-elasticsearch-wazuh-alerts-3-x-2020-05-30/235038/6) thread.

Not sure what changed between 7.17 and 8.12. Perhaps the change in ECS compatibility described in the _Breaking changes_ section of the [8.0 release notes](https://www.elastic.co/guide/en/logstash/current/logstash-8-0-0.html).
