Property 'xy' of type 'z' is not assignable to 'string' index type 'UntypedHandleCall'. for class properties

[jeengbe]

Implementations of services like:

export class GrpcAccountService extends UnimplementedAccountServiceService {
  constructor(private readonly service: AccountService) {
    //        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Property 'service' of type 'AccountService' is not assignable to 'string' index type 'UntypedHandleCall'.
    super();
  }
}

don't allow any class members other than [method: string]: grpc_1.UntypedHandleCall;.

I don't see a way around this other than patch-removing that signature, which leaves the issue here:

  server.addService(
    GrpcAccountService.definition,
    new GrpcAccountService(services.accountService)
    // ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Argument of type 'GrpcAccountService' is not assignable to parameter of type 'UntypedServiceImplementation'.
  );

The best solution to this I've found is patching and as-any'ing it, however very inelegant.
