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
Filebeat Fortinet have error message - Elastic Stack / Beats - Discuss the Elastic Stack

They all are way out of date.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

But it dit not work.
