When I call _activeDirectoryClient.Groups.AddGroupAsync(group) where group's displayname is larger than 120 char, it throws the following exception:
Microsoft.Data.OData.ODataErrorException: Unsupported or invalid query filter clause specified for property 'displayName' of resource 'Group'. ---> System.Data.Services.Client.DataServiceQueryException: An error occurred while processing this request. ---> System.Data.Services.Client.DataServiceClientException: {"odata.error":{"code":"Request_UnsupportedQuery","message":{"lang":"en","value":"Unsupported or invalid query filter clause specified for property 'displayName' of resource 'Group'."}}} at System.Data.Services.Client.BaseAsyncResult.EndExecute[T](Object source, String method, IAsyncResult asyncResult) at System.Data.Services.Client.QueryResult.EndExecuteQuery[TElement](Object source, String method, IAsyncResult asyncResult)
PS: I asked this in Microsoft Graph github. But, I was told to post it here instead.
