Dear Microsoft Team,
We have a solution called Boxafe developed by us ( QNAP Systems Inc) helps customers to backup their M365 SAAS data to QNAP's local storage. This includes backup of Email, contacts, Calendar, One Drive Files, Sharepoint files, Teams data.

One of our customers is facing issue with few of his sharepoint sites to backup. Can you help with this. following are the details.
We encountered a potential bug when using Microsoft Graph API to query SharePoint list items, this request is generated based on the @odata.nextLink returned from M365.

Request:
https://graph.microsoft.com/v1.0/sites/sahsml.sharepoint.com,aabe8d71-af12-434e-bf5d-4f06120ffd58,97812599-2b7c-45c7-88c0-8712de10b789/lists/2a2ef00b-a8ab-47ad-95d0-becddf239a5f/items?$select=sharepointIds%2CparentReference&$expand=driveItem(%24select%3DparentReference)&$top=1000&$skiptoken=UGFnZWQ9VFJVRSZwX0lEPTE0MTgwOCZpeF9QYWdlZD1UUlVFJml4X0lEPTE0MTgwOCZpeF9LZXk9RjNCODI5RTMzQkI3NEJCNEFCRjE1OTM5NUI3MUMyMEE

Response:
{'error': {'code': 'invalidRequest', 'message': 'One of the provided arguments is not acceptable.', 'innerError': {'code': 'badArgument', 'date': '2025-04-13T18:04:34', 'request-id': 'e9803381-6a9f-4fa3-aaac-f591f7d20235', 'client-request-id': 'e9803381-6a9f-4fa3-aaac-f591f7d20235'}}}

Start with the supplied Microsoft Graph v1.0 SharePoint list-items request and its invalidRequest response, then compare the generated @odata.nextLink parameters with the original query. Done means determining whether the request is reproducibly invalid and documenting the confirmed cause or required API correction.
