Description
Running InfluxDB 2.0
This is my code of save data to influxDB
Running flux query
from(bucket: "test-idm-bucket")
|> range(start: v.timeRangeStart, stop: v.timeRangeStop)
|> filter(fn: (r) => r["equipmentNo"] == "3fb38f9c-be57-43bd-bf1b-ede34df20d22")
|> filter(fn: (r) => r["_field"] == "ljll")
|> sort(columns: ["_time"], desc: true)
Return result
I find it that sort function doesn't work. Is it caused by my re-assignment to _time?

Research direction
Start by reproducing the provided Flux query against InfluxDB 2.0, including the reassignment to _time, and compare the returned ordering with sort(columns: ["_time"], desc: true). No source file or test is named; determine whether the behavior is caused by the reassignment, then identify the relevant implementation or test and confirm the corrected ordering.
