Support nested expansion deserialization - ex Read SharePoint List

Hi team,

I am a bit of a rookie but keen to see if this is an issue or if I am doing something wrong. I have searched everywhere but can't seem to find a solution so sorry if this is the wrong place to log this.

I am trying to read the data from a SharePoint list. It is working within the API explorer but not when I move it into PHP. In the API explorer I am hitting the below endpoint:

https://graph.microsoft.com/v1.0/sites/{site-id}/lists/{list-id}/?expand=columns,items(expand=columns)

When I do the below code in PHP it brings back the columns but the items are coming back in an empty array:

$list = $graph->createRequest("GET", "/sites/{site-id}/lists/{list-id}/?expand=columns,items(expand=columns)")
->setReturnType(Model\Site::class)
->execute();

Any help would be really appreciated!

Thanks

まず、Model\Site::class を戻り値の型として使用して、/sites/{site-id}/lists/{list-id}/?expand=columns,items(expand=columns) に対する PHP の createRequest 呼び出しを再現し、API Explorer のレスポンスと比較します。ネストされた items とその columns がどのようにデシリアライズされるかを追跡し、返された items に空の配列ではなく展開されたデータが含まれていることを確認します。
