Fetching allMembers fails for public and private channels

Describe the bug

According to the documentation the allMembers endpoint can be used for any channel type. This can be confirmed using the Graph Explorer or manualy invoking that endpoint.

However, when using the SDK to fetch all members for any channel that is not shared the request fails.

com.microsoft.graph.models.odataerrors.ODataError: Failed to execute GetThreadRosterAsync.

Expected behavior

The request should work for any channel type (as it does when using the members() endpoint insted of allMembers().

How to reproduce

graphClient.teams()
    .byTeamId(team.getId())
    .channels()
    .byChannelId(channel.getId()) //use a private or public channel here
    .allMembers()
    .get(); //the error occurs at this point unless the provided channel has MembershipType.Shared

Issue にある Java 再現から始めて AllMembersRequestBuilder.get を調べ、生成された allMembers と members のリクエストパスを、パブリック、プライベート、共有チャンネルについて比較します。ドキュメント化された allMembers エンドポイントに照らして動作を確認し、不一致が SDK のリクエストにあるのかサービスにあるのかを特定します。完了条件は、問題のあるチャンネルタイプが一貫して処理されるか、問題が明確にサービス側として特定されることです。
