Things to note when designing for empty state: 
1. Have some graphic that makes the situation less disappointing. Talk with a fun personality if you can. 
2. Avoid user-unfriendly words like " cannot" "unable" "fail 😱" "error 😱" "wrong 😱" . 
3. Be reasonable. Explain possible reasons. 
4. Be helpful. Suggest solutions. 
5. Be straightforward. Give one and only one button that most likely can get out from here.
