I get an error displayed in 2 panels

Hello everyone,
First of all, sorry for using Google Translate, but my English isn’t that good anymore.
I have a dashboard with 7 panels in Influx. 5 of them are displayed normally and do not cause any problems with Grafana either. With 2 panels I have recently had an error message for 3 days. I’m also surprised that I only get the error message on 2 panels, since the query is identical on all 7. Only the measuring point is different.
This is the code from my panels

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")

Can you explain to me how I can get rid of the error, or what I have to do exactly, since I’m not really familiar with Influx.

Hi @Damrak2023 could you let us know what version of InfluxDB you are running? I believe this was an issue we had in 2.5 and solved by 2.6.1 but could be wrong.

Yes, I am using 2.6.1 - see here:

Hello everyone,
Does anyone have an idea how I can get rid of this error? It would be really great if one of you could help me here.

Greetings Andy
