Hi. Im trying to use the today() function with Grafana but im getting the error:

Screenshot_3

My query:

from(bucket:"DATABASE")
  |> range(start: today())
  |> filter(fn: (r) =>
    r._measurement == "MEA1" and
    r._field == "value"
  )
  |> yield()

Hello @ShoTz,
What version of InfluxDB are you running?
The today() function is only available with Flux * 0.116.0+ which might not be included with your version.
