Facing issue while Uploading file to GCS from Google Cloud Compute

Facing issue while uploading the file to GCS from Google Cloud Compute - from Linux VM.

We are using gcloud gsutil cp "FILE_NAME" "${GCS_BUCKET}/${GCS_OBJECT}" .

It works from the compute to push in the shell session.

But when we are calling this from multiple shell sesssions (Example A-Script is calling B-Script and B-Script is calling C-Script and C-Script has the code to push it to GCS and , it is unable to push the files to GCS and giving error.
```

During handling of the above exception, another exception occurred:

```

GSUTIL is not configured properply in the cloud.

However **gcloud auth list** work properly. in the same C-Script (3 rd hierarchy shell)

Start by reproducing the `gsutil cp` command from the nested C-Script on the Linux VM, comparing it with the working interactive shell session. Check the traceback around `httplib2` and `storage.googleapis.com`, and compare the environment with `gcloud auth list`. Done means identifying a reproducible cause and documenting or fixing the failed upload path.
