I am working on another simple 'liker' twitter bot that I'm trying to host on Heroku based off your tutorial and how you mentioned the Heroku server to host.
I want it to like 10 tweets every 24hours regardless of whether my computer is on or off. I used the Heroku CLI to deploy the bot and it's been deployed here: https://liker-bot-1000.herokuapp.com/ , but alway the Application Error page. So I looked at the error log, added "start" to my package.json script, tried redeploying it, but it's still not there. Do you know if this is common server deployment problem?
