[CONTROLLER-231] RPC Methods with no args fail to return the result

Duplicate — Tue, 25 Jul 2023 08:23:17 +0000

In RestConfImpl, when RPC methods that have no input arguments are implemented, they fail to return the result. The implementation returns a valid result object, but somewhere down the line, most likely in RestConfImpl's invokeRPC method, the result object becomes null. The user, as a result, gets a HTTP 204 No Content for their query. There are no exceptions printed out.

If I change the RPC to accept a dummy input argument, everything else remaining same, things work fine.
