The sender can't get the error message from receiver

[wenfengwang]

Hi sdk-go community, I started a receiver like:

func receive(ctx context.Context, event cloudevents.Event) cloudevents.Result {
	fmt.Printf("Got an Event: %s", event)
	return cloudevents.NewHTTPResult(401, "test")
}

but the sender can't get the error message:

and I found in https://github.com/cloudevents/sdk-go/blob/main/v2/protocol/http/protocol.go#L366, that only StatusCode be used, but Format and Args are ignored.

I was wondering if it was a bug?
