[Solved] Logs: Funktion $_timeFilter not defined

I have a problem with getting data from a table:

let _index = 2;
| where $__timeFilter(timestamp)
| where operation_Name matches regex "^/.P./$"

Here Grafana shows me the error “The function ‘$__timeFilter’ is not defined.”

I Run Grafana version “v8.2.2 (6232fe07c0)”.

OK, obviously it’s only a display bug of the editor. The request is executed and shown correctly!
