2 panels show me an error

Hello everyone,
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?

No idea @damrak2022 , but this definitely seems to be an InfluxDB error that Grafana is simply a victim of. Did you already read through & try suggestions from this?
