Cannot get Azure subscriptions using Azure Python SDK

I can get Azure subscriptons list using REST API.

However, when I'm switching to Azure Python SDK, there seems to be some problems.

This is the code so far:

from azure.identity.aio import ClientSecretCredentialfrom azure.mgmt.resource import SubscriptionClientimport jsondata = json.load(open("parameters.json"))credential = ClientSecretCredential(    tenant_id=data["tenant"],    client_id=data["client_id"],    client_secret=data["client_secret"],)subs = SubscriptionClient(credential=credential)l = list(subs.subscriptions.list())print(l)

I use an additional list in the pnultimate line because subs.subscriptions.list() returns an iterator. Despite that, the code seems pretty straightforward.

However, this code gives the following error:

Traceback (most recent call last):  File "c:\Users\azureuser\Documents\GitHub\vmss-scripts\vm_create.py", line 14, in <module>    l = list(subs.subscriptions.list())        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^  File "C:\Users\azureuser\scoop\apps\python\current\Lib\site-packages\azure\core\paging.py", line 123, in __next__    return next(self._page_iterator)           ^^^^^^^^^^^^^^^^^^^^^^^^^  File "C:\Users\azureuser\scoop\apps\python\current\Lib\site-packages\azure\core\paging.py", line 75, in __next__    self._response = self._get_next(self.continuation_token)                     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^  File "C:\Users\azureuser\scoop\apps\python\current\Lib\site-packages\azure\mgmt\resource\subscriptions\v2022_12_01\operations\_operations.py", line 526, in get_next    pipeline_response: PipelineResponse = self._client._pipeline.run(  # pylint: disable=protected-access                                          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^  File "C:\Users\azureuser\scoop\apps\python\current\Lib\site-packages\azure\core\pipeline\_base.py", line 230, in run    return first_node.send(pipeline_request)           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^  File "C:\Users\azureuser\scoop\apps\python\current\Lib\site-packages\azure\core\pipeline\_base.py", line 86, in send    response = self.next.send(request)               ^^^^^^^^^^^^^^^^^^^^^^^  File "C:\Users\azureuser\scoop\apps\python\current\Lib\site-packages\azure\core\pipeline\_base.py", line 86, in send    response = self.next.send(request)               ^^^^^^^^^^^^^^^^^^^^^^^  File "C:\Users\azureuser\scoop\apps\python\current\Lib\site-packages\azure\core\pipeline\_base.py", line 86, in send    response = self.next.send(request)               ^^^^^^^^^^^^^^^^^^^^^^^  [Previous line repeated 2 more times]  File "C:\Users\azureuser\scoop\apps\python\current\Lib\site-packages\azure\mgmt\core\policies\_base.py", line 46, in send    response = self.next.send(request)               ^^^^^^^^^^^^^^^^^^^^^^^  File "C:\Users\azureuser\scoop\apps\python\current\Lib\site-packages\azure\core\pipeline\policies\_redirect.py", line 197, in send    response = self.next.send(request)               ^^^^^^^^^^^^^^^^^^^^^^^  File "C:\Users\azureuser\scoop\apps\python\current\Lib\site-packages\azure\core\pipeline\policies\_retry.py", line 531, in send    response = self.next.send(request)               ^^^^^^^^^^^^^^^^^^^^^^^  File "C:\Users\azureuser\scoop\apps\python\current\Lib\site-packages\azure\core\pipeline\policies\_authentication.py", line 124, in send    self.on_request(request)  File "C:\Users\azureuser\scoop\apps\python\current\Lib\site-packages\azure\core\pipeline\policies\_authentication.py", line 100, in on_request    self._update_headers(request.http_request.headers, self._token.token)                                                       ^^^^^^^^^^^^^^^^^AttributeError: 'coroutine' object has no attribute 'token'sys:1: RuntimeWarning: coroutine 'GetTokenMixin.get_token' was never awaited

I don't know what was missing, and the error didn't gives much information.

It seems it was related with token. I can get a token with the following method:

async def print_token():    token = await credential.get_token("https://management.azure.com/.default")    print(token.token)    await credential.close()asyncio.run(print_token())

But it requires asyncio to run, which isn't compatible with my code. And where should I should put the token?

I've investigated the source code if Azure CLI. It seems it get subscriptions using the same method:https://github.com/Azure/azure-cli/blob/f369cead2604e37480611b0cc269fee615956ea2/src/azure-cli-core/azure/cli/core/_profile.py#L835

The client was acqurired from the function below, and the type was

https://github.com/Azure/azure-cli/blob/f369cead2604e37480611b0cc269fee615956ea2/src/azure-cli-core/azure/cli/core/profiles/_shared.py#L60

Which is essentially the SubscriptionClient.
