Failed to filter based on file property in MS Graph API

Question

https://graph.microsoft.com/v1.0/me/drive/root:/{folderName}:/children?$top={top}&$filter={filter}, {filter}=file eq null, this Graph API works before, but now it return

"error": {

    "code": "notSupported",

    "message": "Operation not supported"

}
```for some outlook acocunt, while works on some other account. 

The description in [https://learn.microsoft.com/en-us/onedrive/developer/rest-api/concepts/filtering-results?view=odsp-graph-online#filterable-properties](https://learn.microsoft.com/en-us/onedrive/developer/rest-api/concepts/filtering-results?view=odsp-graph-online#filterable-properties) is confusing, it seems to say 1. it only support filter on name and url, and also  2. all properties(including file and folder) but some properties are not so efficient? 

I‘d like to know whether file/folder is supported for filter. Hopefully current failure is a bug which would be fixed.

Hi @Dai, Coco

Please check your drive type, for OneDrive for Business, SharePoint Online and SharePoint Server 2016, filtering support only name and url properties.

Hope this helps.
