Command not working anymore within python script, but still working with cli

Describe the bug

Command Name az network vnet list

Errors:

The credential data used by CLI has been expired because you might have changed or reset the password. Please clear browser's cookies and run 'az login'

To Reproduce:

Script to reproduce the behavior.

#!/usr/bin/python3
from azure.cli.core import get_default_cli

def azurer(args_str):
    args = args_str.split()
    cli = get_default_cli()
    cli.invoke(args)
    return cli.result.result

subscriptions = azurer("account list")
for s in subscriptions:
    vnets = azurer("network vnet list --subscription " + s['name'])
    if type(vnets) == dict:
        for v in vnets:
            print(v['name'])

Expected Behavior

Last time I used this script (some weeks ago) it was working fine. Also, the same command (network vnet list --subscription xxxxxx) executed from the CLI is still working fine.

Environment Summary

Linux-4.4.0-19041-Microsoft-x86_64-with-debian-bullseye-sid, Ubuntu 20.04.3 LTS
Python 3.6.10
Installer: DEB

azure-cli 2.30.0

Additional Context

I’ve cleared my account (az account clear) and tried again, same result. I’ve also tried with this environment:

Windows-10-10.0.19041-SP0, 
Python 3.9.4
Installer: PIP

azure-cli 2.30.0

obtaining this output:

User xxxxxxxxxxxxxxx does not exist in MSAL token cache. Run `az login`.

Thanks a lot @jiasli, I’ve been able to solve the issue!

This is because the Python script and direct az network vnet list command are calling different versions of Azure CLI.

The error message The credential data used by CLI ... has long been removed by #17072. Please make sure the correct version of Azure CLI is called by upgrading to the latest version

pip install --upgrade azure-cli

By the way, your script uses subscription name as --subscription which may break if there are spaces in it. You can use either subscription ID of shlex.split.

Use subscription ID:

from azure.cli.core import get_default_cli


def azurer(args_str):
    args = args_str.split()
    cli = get_default_cli()
    cli.invoke(args)
    return cli.result.result

subscriptions = azurer("account list")
for s in subscriptions:
    vnets = azurer("network vnet list --subscription " + s['id'])
    if type(vnets) == dict:
        for v in vnets:
            print(v['name'])

Use shlex.split:

from azure.cli.core import get_default_cli
import shlex


def azurer(args_str):
    args = shlex.split(args_str)
    cli = get_default_cli()
    cli.invoke(args)
    return cli.result.result

subscriptions = azurer("account list")
for s in subscriptions:
    vnets = azurer("network vnet list --subscription '" + s['name'] + "'")
    if type(vnets) == dict:
        for v in vnets:
            print(v['name'])
