InfluxDB showing invalid memory address when filtering value which donot exists

[pratikdas44]

**Wanted - Filter out the value in influxdb, for which a point does not exists

Expected behavior: InfluxDB should show nothing (no error should come)

Actual behavior: InfluxDB showing invalid memory address or nil pointer dereference**

**Environment info:

InfluxDB version: 2.0.9 where the query is working, and 2.4.0 where query is not working**

Below is the query -

import "strings" import "date" import "regexp" src_bucket = "test_bucket" src_measurement = "gnb_om" start_time = 2023-03-28T04:00:00Z stop_time = 2023-03-28T05:00:00Z

from(bucket: src_bucket) |> range(start: start_time,stop: stop_time) |> filter(fn: (r) => r["_measurement"] == src_measurement) |> filter(fn: (r) => r["_field"] == "VS_HO_Msg3RcvdCountforSgNBAddition" or r["_field"] == "OR_ENDCPROCEDURE_SgnbAddAttemptCell" ) |> truncateTimeColumn(unit: 1m) |> toFloat() |> group(columns: ["_time","NID","cell"]) |> aggregateWindow(every: 1h, fn: count) //|> filter(fn: (r) => r["_value"] == 1) |> yield(name: "count") |> findRecord(fn: (key) => true, idx: 0)
