I’m making a simple query:
from(bucket: "Bucket") |> range(start: v.timeRangeStart, stop: v.timeRangeStop) |> filter(fn: (r) => r._measurement == "gps") |> group(columns: ["device"], mode:"by")
which returns some result but also an error
expected integer cursor type, got *reads.floatMultiShardArrayCursor
If I would remove last line with group function there would be no error.
Does anybody know what is the reason
