   Actually, we don't know the revision from nacos server. `Get` before `Sub` or `Sub` before `Get` cannot solve the issue. Also, I found there maybe a concurrent issue there. According to nacos' maintainer, nacos will notify the latest data once `Sub`. So, for the result, even `Get` return empty provider, `Sub` will notify the latest providers and then `Directory` will be synced.
