Released v3
https://signlookbucket.herokuapp.com/ deployed to HerokuAre these the logs from “heroku logs —tail”?
Sure, I just upload folder without running npm install, is it ok ?
After successfully running on local machine, I have pushed my project to heroku to run online but it does not work correctly.

What should i do now?
