Hi folks!

I'm running a query, through EQL, for event correlation, however, it's returning a syntax error. The strange thing is that the same query is made in another Elastic SIEM and it doesn't return an error. Has anyone had these problems?

I currently use Elastic SIEM version 7.16.1 on both servers on one of them it worked. In the other not. I tested it on version 14 and it worked. This occurs on my second server that I monitor.

```auto

```
