Flux Query on Command Prompt

Question

I've been trying Flux query on command prompts few hours for simple query. I'm using InfluxDB 2.7 and InfluxDB-Client 2.7.3. Here is how my data look like in my bucket first

_measurement	_field	_value	_time
airSensors	co	0.1	2023-07-14T00:36:52Z
airSensors	co	0.2	2023-07-14T00:37:02Z

This is my query from(bucket: "first") |> range(start: 2023-07-14T00:00:00Z, stop: now()) |> filter(fn: (r) => r["_measurement"] == "airSensors"). It runs success fully in Data Explorer but not command prompt. I got not idea why is this happening. I've attached a image with my trials, where the query is runnable in Data Explorer but not command promp. Can someone help out?

Solved the problem by myself.

The query string should be enclosed with double quote ", value within the query should be escaped with backslash \ only follow by double quote ".
