When a new object is created using the Graph API e.g. a user, the URL that is returned in the Location header does not contain the API version that was used.
As such when the object is accessed using the URL, any operations on the new object fail with the error when using an OData library (e.g. WCF Data Services, Olingo, etc.):
{"odata.error":{"code":"Request_DataContractVersionMissing","message":{"lang":"en","value":"The specified api-version is invalid. The value must exactly match a supported version."}}}
