ListItem metadata returned by the SDK is different from what is returned from the API

[devistollon]

Describe the bug

I am trying to retrieve the ListItem related to a specified DriveItem

I am using the following code:
list_item = await self.graph_client.drives.by_drive_id(self.drive_id).items.by_drive_item_id(drive_item_id=drive_item_id).list_item.get()

After parsing the response, I’ve noticed that some fields in the output have different values compared to those returned by the Graph API playground.

Below is the output with the fields that differ:

// Python SDK Output
{
  //... other fields
  "_Revision": "2024-09-30T02:00:00Z",
  "AuthorLookupId": "2024-09-30T06:00:00Z",
  "EditorLookupId": "2024-09-30T10:00:00Z",
  "ItemChildCount": "2024-09-30T00:00:00Z",
  "FolderChildCount": "2024-09-30T00:00:00Z",
  "_UIVersionString": "2024-09-30T19:00:00Z"
}

// Graph API Playground Output
{
    //... other fields
    "_Revision": "02",
    "AuthorLookupId": "6",
    "EditorLookupId": "10",
    "_UIVersionString": "19.0"
}

For example, the correct _Revision field value is "02", but the SDK returns it as a date. The same issue appears with other standard SHP fields, which are numbers but are somehow converted to dates by the SDK.

Why does this behavior occur?

Expected behavior

I expect that the SDK returns the same value present in the Graph API Playground.

How to reproduce

• Authentication with ClientSecretCredential class from the azure.identity.aio module;
• Invoke the function above by passing a drive_id and a drive_item_id;

Hello @devistollon thanks for using the SDK and for raising this.

On this, we have had a scenario where a number of numeric fields are converted to datetime objects, this has been fixed in the latest version of the json serialization library, check out microsoft/kiota-serialization-json-python#358 and upgrade the library to the latest version.

Hope this helps?

Hi @shemogumbe,
I've forced the upgrade of the msgraph-sdk library and now everything works fine.

Thank you
