Not able to get the items for a particular drive/onedrive

Question

I got a drive id from a Microsoft Teams generated SharePoint site list using

https://graph.microsoft.com/v1.0/groups/group-id/sites/root/lists/list-id/drive

I can successfully get the details of the drive by calling:

https://graph.microsoft.com/beta/drives/drive-id

However, I am getting an invalid request error when trying to get the items of the drive

https://graph.microsoft.com/beta/drives/drive-id/items

{
    "error": {
        "code": "invalidRequest",
        "message": "The request is malformed or incorrect.",
        "innerError": {
            "request-id": "0d83a954-ed79-4a4a-ae28-f963db4b6f2f",
            "date": "2018-03-26T05:10:37"
        }
    }
}

You're URI is a little off. You can only use the items path when referencing a specific DriveItem (i.e. /drives/{id}/items/{id}).

If you're looking for a collection of DriveItem resources in a drive, you need to call /drives/{driveId}/{path}/children. The {path} is the folder you want to retrieve the catalog of DriveItem resources from. For the "root" directory you can simply use root:

https://graph.microsoft.com/v1.0/drives/{driveId}/root/children

Also, you generally shouldn't use the beta version of Microsoft Graph. It can experience breaking changes without warning (and does). It isn't safe for production use.
