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

Start by reproducing the PHP createRequest call for /sites/{site-id}/lists/{list-id}/?expand=columns,items(expand=columns), using Model\Site::class as the return type, and compare it with the API Explorer response. Trace how nested items and their columns are deserialized, then verify that the returned items contain the expanded data rather than an empty array.
