**Good afternoon I'm trying to configure an alert in a unitary way, I mean, that from a field, I get out or equal to a term that I define; what I need is a term that I ask from the field "monitor.name.keyword" to get from that field a name that I put with a query term filter. This is the code and the error you give me in the output.**
