Panic: runtime error: invalid memory address or nil pointer dereference - on arm64

Hello,
I have installed Influxdb 2.0 on ARM64 regarding the documentaton.
Basic queries are working, but if I use things like mean:

from(bucket: “test-hystreet”)
|> range(start: v.timeRangeStart, stop: v.timeRangeStop)
|> filter(fn: ® => r["_measurement"] == “hystreet”)
|> filter(fn: ® => r["_field"] == “pedestrians_count”)
|> group(columns: ["_time"])
|> mean()
|> group(columns: ["_value", “_time”], mode: “except”)

I run into error:

 panic: runtime error: invalid memory address or nil pointer dereference

regards,
Thomas
