Use in React/Redux

[Janaka-Steph]

I would appreciate some help using the stubs in React/Redux.
Here client.join(JoinRequest.create(), metadata) is expected to return a type JoinReply but returns a type SurfaceCall.
What am I missing?

export const rewardApi = towerApi.injectEndpoints({
  endpoints: (build) => ({
    join: build.query<JoinReply, void>({
      queryFn: async (arg, { getState }) => {
        const state = getState() as RootState;
        const client = selectRewardClient(state);
        const metadata = selectMacaroon(state);
        return retryRtkRequest(async () => ({
          data: client.join(JoinRequest.create(), metadata),
        }));
      },
    }),
  }),
});

Thanks in advance

Sorry I found my mistake. I was trying to use grpc client for NodeJS in the browser.
