Cannot seem to use deserializeBinary manually

I'm having an issue in gRPC that's been driving me crazy. I have a .NET gRPC service that my ReactJS client is connecting to - this works fine. I'm subscribing to my stream, and I get data over the stream as expected. I'm having an issue deserializing "bytes" or "google.protobuf.Any" types that exist in my messages. The one I'm receiving looks like this:

message PointNotification {
  Point.KindsOfPointNotification Kind = 1;
  bytes NotificationData = 2;
}

In this case the bytes represent the following proto message, but it could be a variety of other messages:

message NotificationPointRemoved
{
    PointEntity Point = 1;
}

message PointEntity {
    Core.Types.EntityId Identifier = 1;    
    Core.Types.EntityLocation Location = 2;
    google.protobuf.Timestamp LastModifiedTime = 3;
}

Inside of the ReactJS client I am doing the following:

    useEffect(() => {
        console.log("Subscribing to point stream");
        var pointStream = client.subscribeToNotificationStream(new Empty(), {});
        pointStream.on("data", (response) => {
            switch (response.getKind())
            {
                case KindsOfPointNotification.KINDS_OF_POINT_NOTIFICATION_POINT_ADDED_OR_UPDATED:
                    console.log(NotificationPointAddedOrUpdated.deserializeBinary(response.getNotificationdata()));
                    break;
                case KindsOfPointNotification.KINDS_OF_POINT_NOTIFICATION_POINT_REMOVED:
                    console.log("Point removed");
                    break;
            }
        });

When I call deserializeBinary I get an uncaught exception in the browser that says:

I've also tried this with the google.protobuf.Any type with similar, but slightly different results that you can read about here:

This seems like an actual issue in grpc-web to me so I thought it prudent to bring to people's attention here. Does anyone know how to resolve this issue?
