question

Hi @BritneyTu-4797

Please see this document: Sorting collections:

Note that in OneDrive for Business and SharePoint Server 2016, the orderby query string only works with name and url.

Sharepoint online is actually OneDrive for Business.

So filtering by lastModifiedDateTime is not supported in this case. It is supported for OneDrive Personal.
