Versions:

Querying a model (with Nhibernate mapping) with OData.
Note: All other query options like $expand, $orderby, $filter, $select etc are working as expected except GroupBy and Aggregate
Using OData GroupBy query as below :
https://localhost:65000/api/Model?$apply=groupby((userName))
Gives below exception:
Using OData Aggregate query as below :
https://localhost:65000/api/Model?$apply=aggregate(Rank%20with%20max%20as%20MaxRank)
Gives below exception:
