I have a dashboard with 7 panels, all of which worked without any problems until 2 days ago. But since 2 days I get the following error displayed in two panels - see Image-1
The code is identical in all panels, only a different device is monitored at a time.
from(bucket: "DBANDY1") |> range(start: v.timeRangeStart, stop: v.timeRangeStop) |> filter(fn: (r) => r["_measurement"] == "Laufzeit_Imac") |> filter(fn: (r) => r["_field"] == "value") |> aggregateWindow(every: v.windowPeriod, fn: mean, createEmpty: false) |> yield(name: "mean")
First of all, I don’t understand why the error only appears in 2 and not in all 7 panels.
In Grafana it looks like this:
Can you tell me how to fix the error? What do I have to do exactly?
