I'm using Flux to do a search, when the query has more than 1 million rows, the inflow returns me null

I'm using Flux to make a paged query using LIMIT and OFFSET, but when the search in InfluxDB has more than 1 million rows, the inflow returns me null. My query:
```
from(bucket: "PData/autogen") |> range(start: 2018-01-01T09:12:32Z, stop: 2018-01-06T08:00:00Z)
|> filter(fn:(r) => r._field == "Value" and r._measurement == "White" )
|> group(columns: ["_measurement"]) |> sort(columns:["_time"] , desc: true)
|> limit(n: 10, offset: 0)
```
if I shorten the query period where the total row count drops to less than 1 million, the querie works correctly. However as I am using LIMIT and OFFSET I shouldn't even have a row overflow problem because it should only bring 10
