Event loop is closed using RemovePasswordPostRequestBody

Describe the bug

I am trying to delete multiple app secrets in Azure. One key is deleted but it does not advance. I can add secrets just fine. I can delete ONE secret typically. But deleting multiple secrets ends with "Event loop is closed".

Expected behavior

I can add secrets just fine. I can delete ONE secret -- typically. But multiple fail as above.

How to reproduce

This code reproduces the problem:

from msgraph import GraphServiceClient
from azure.identity import ClientSecretCredential
from creds import tenant_id, client_id, client_secret

from msgraph.generated.applications.item.remove_password.remove_password_post_request_body import RemovePasswordPostRequestBody

credential = ClientSecretCredential(
    tenant_id=tenant_id,
    client_id=client_id,
    client_secret=client_secret
)

from uuid import UUID

scopes = ['https://graph.microsoft.com/.default']
graph_client = GraphServiceClient(credential, scopes)

async def show_secrets():
    result = await graph_client.applications.by_application_id(OBJECT_ID).get()
    return result

async def delete_older_secrets():
    try:
        for one_secret in str_not_uuids:
            print(f"== {one_secret}")
            if one_secret == "__CURRENT__":
                print("passing current")
                continue 
            request_body = RemovePasswordPostRequestBody(key_id=UUID(one_secret),)
            result = await graph_client.applications.by_application_id(
                "OBJECT_ID"
            ).remove_password.post(request_body)
    except Exception as e:
        print(e)
    else:
        print('ok')


if __name__ == '__main__':
    import asyncio
    import operator
    all_secrets=asyncio.run(show_secrets())
    str_not_uuids=[str(x.key_id) for x in all_secrets.password_credentials]
    asyncio.run(delete_older_secrets())

Known Workarounds

I can use msal in a non asyncio loop:

import msal
import requests

def remove_application_secrets(tenant_id, client_id, client_secret, secret_ids):

    authority = f"[https://login.microsoftonline.com/{tenant_id}](https://login.microsoftonline.com/%7Btenant_id%7D)"
    app = msal.ConfidentialClientApplication(
    client_id,
    authority=authority,
    client_credential=client_secret

)

result = app.acquire_token_for_client(scopes=["[https://graph.microsoft.com/.default"]](https://graph.microsoft.com/.default%22]))

if "access_token" not in result:
    print(result.get("error"))
    print(result.get("error_description"))
    return

# Remove each secret
headers = {
'Authorization': 'Bearer ' + result['access_token'],
'Content-Type': 'application/json'
}


for secret_id in secret_ids:

try:

   url = f"[https://graph.microsoft.com/v1.0/applications/{object_id}/removePassword] 
   (https://graph.microsoft.com/v1.0/applications/%7Bobject_id%7D/removePassword)"

    payload = {"keyId": secret_id}
    response = requests.post(url, headers=headers, json=payload)
    if response.status_code == 204:
    print(f"Successfully removed secret with ID: {secret_id}")

else:

    print(f"Failed to remove secret {secret_id}. Status code: {response.status_code}")
    print(response.text)

except Exception as e:
    print(f"Error removing secret {secret_id}: {str(e)}")
    remove_application_secrets(

client_id=client_id,
tenant_id=tenant_id,
client_secret=client_secret,
secret_ids=['blah1', 'blah2']
)

Debug output

No response

Bắt đầu bằng cách chạy luồng asyncio.run sử dụng GraphServiceClient, ClientSecretCredential và remove_password.post từ báo cáo, sau đó kiểm tra cách client và credential quản lý các tài nguyên gắn với event loop qua các lần gọi lặp lại. Hoàn thành khi việc xóa nhiều application secret hoàn tất mà không có "Event loop is closed" và hành vi này được bao phủ bởi một regression test.
