Python GCP API not able to read environmental values

Question

Developing a DLP client and Setting GOOGLE_APPLICATION_CREDENTIALS using win shell.

API is failing with following signature:

google.auth.exceptions.DefaultCredentialsError: File "XXXXX.json" was not found.

When set in code using

os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = "XXXXX.json" it works fine.

OS used windows 10.

Can any one explain the reason?

Updates

I did set environment variable from pycharm terminal.
I am running the code from pycharm terminal: python my_code.py
When i print(os.environ["GOOGLE_APPLICATION_CREDENTIALS"]) i get the value i did set.

I recommend verifying it's set by logging them using print(os.environ) — Jordanna Chord, Dec 01 '20 at 04:21
Did you reboot? (Windows magic tips!!!). Else, how are you running your code? You talk about win shell. Do you run it in command line? With your IDE? — guillaume blaquiere, Dec 01 '20 at 19:36
@DustinIngram I am using absolute path. I used the same path in both the scenarios. — Arnab Mukherjee, Dec 02 '20 at 06:38
@guillaumeblaquiere I am running the code from pycharm terminal. I did set the env variables there. — Arnab Mukherjee, Dec 02 '20 at 06:40

Issue Found:

Environmental variable was set using quotes. It should be without quotes.

set GOOGLE_APPLICATION_CREDENTIALS="path\to\secret\key"

Confusing debug message

google.auth.exceptions.DefaultCredentialsError: File "path\to\secret\key" was not found.

Resolution:

set GOOGLE_APPLICATION_CREDENTIALS=path\to\secret\key
