Issue details

I run this code:

from azure.mgmt.billing import BillingManagementClient
from azure.identity import ClientSecretCredential

credentials = ClientSecretCredential(
    tenant_id="<TenantID>",
    client_id="<ClientID>",
    client_secret="<ClientSecret>",
    api_version="2020-05-01"
)

client = BillingManagementClient(
    credential=credentials,
    subscription_id='<SubscriptionID>',
)

response = client.invoices.list_by_billing_profile(
    billing_account_name="<BillingAccount>",
    billing_profile_name="<BillingProfile>",
    period_start_date="2024-02-01",
    period_end_date="2024-02-29",
)
for item in response:
    print(item)

I don't get an invoice in return.

Expected behavior

An invoice description in JSON format.

Actual behavior

The sample code give me this output:

If I change to

for item in response:
    print(item.serialize())

I get this output:
{}

Reproduction Steps

Environment
