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

首先运行报告中的 asyncio.run 流程，使用 GraphServiceClient、ClientSecretCredential 和 remove_password.post，然后检查客户端和凭据如何在重复调用期间管理其绑定到事件循环的资源。完成标准是删除多个应用程序机密时不会出现 "Event loop is closed"，并且该行为由回归测试覆盖。
