Group members request gives an incomplete list

L'issue non nomina alcun file del repository né alcun test. Inizia eseguendo la riproduzione Python fornita con le versioni indicate di msgraph-beta-sdk e msgraph-core, quindi esamina la richiesta dei membri del gruppo di GraphServiceClient e il relativo comportamento di paginazione o espansione. Il lavoro è completato quando l'SDK restituisce tutti i membri diretti del gruppo, incluso il service principal, invece dei soli primi 20.

Describe the bug

I am trying to use Ansible to update membership of an Entra group with managed identities in it. It is misbehaving because the list of members it gets back from the GraphServiceClient is incomplete - in my case, only 20 of the 35 members listed in the Azure portal actually show up, even with the msgraph_beta SDK.

Expected behavior

A list of all the users in the Direct Members section of the group in the Azure portal.

How to reproduce

SP is created with:

az identity create -g {{ resource_group }} -n {{ application_name }}-mi -o json

Attached is a minimal(ish) test example to get members from a group and also fetch a single service principal (that should be in the group but isn't) by object_id. The SP does exist, with odata_type='#microsoft.graph.servicePrincipal'
