Answer 1

I know it's late to answer this, but anyway i'll do it. I too faced with this problem many times. Then I found that it is caused by unstable internet connection. Try with other networks and you may be able to deploy, or try restarting your internet connection.

Answer 2

I had issues with this when deploying while using a VPN like tunnelbear. Try disabling that and see if it helps.

I have also tried deleted my cloud functions from google cloud console before trying to deploy again, which has helped in other similarly weird circumstances. https://console.cloud.google.com/functions/list?project=
