In graph explorer, I am trying to execute OData queries with the filter startswith on list items. All of the OData filter startswith functions I tried to return itemNotFound error. See an example below https://graph.microsoft.com/v1.0/sites/root/lists('Documents')/Items?$filter=startswith(webURL, 'https') eq true
Graph explorer has Sites.ReadWrite.All scope.
Can someone point me to any documentation on the extent of OData features supported in Microsoft Graph?
SharePoint List API (and Graph API on drives/OneDrive API) do not support filtering or ordering results. As you may know, both SharePoint Document and OneDrive can be accessed by the Drive api. When Microsoft Graph sees a query parameter it doesn't expect, it simply ignoring the unknown filter parameter and returning us an unfiltered result. The drives api supports the $expand, $select, $skipToken, $top, and $orderby(orderby does not work on my side) OData query parameters to customize the response.
The currently available documentation just states:
Support for $filter operators varies across Microsoft Graph APIs.
The word varies might be the inference that these options are not totally supported across all products in Graph.
