Python Graph API Client Exception - ValueError: not enough values to unpack (expected 2, got 1)

I am following the guide on: https://github.com/microsoftgraph/msgraph-sdk-python to build a Python package that can pull all my devices from Azure AD (Entra). I have confirmed good working API credentials and that they have the right permissions:

My code is below

async def get_AADdevices():
    MScredential = ClientSecretCredential(
        tenant_id=os.environ['MSGraphTenantID'],
        client_id=os.environ['MSGraphClientID'],
        client_secret=os.environ['MSGraphClientSecret']
    )
    scopes = ['https://graph.microsoft.com/.default']
    client = GraphServiceClient(credentials=MScredential, scopes=scopes)
    devices = await client.devices.get()

I am getting the following error when it calls the await client.devices.get():

Any ideas?

I am expecting it to return a list of devices
