I see that there has been a lot of questions about this like these ones : [[Filebeat][Fortinet Module] Failed to parse field - Elastic Stack / Beats - Discuss the Elastic Stack](https://discuss.elastic.co/t/filebeat-fortinet-module-failed-to-parse-field/273437#!)  
[Filebeat Fortinet have error message - Elastic Stack / Beats - Discuss the Elastic Stack](https://discuss.elastic.co/t/filebeat-fortinet-have-error-message/258261#!)

They all are way out of date. So has there been any update on the module since then ?

And yes, I tried using the pattenrs they gave here [[Filebeat Fortinet Module] Include more Grok Pattern · Issue #23246 · elastic/beats · GitHub](https://github.com/elastic/beats/issues/23246)

But it dit not work.
