Node.js app on Heroku failing, unsure why

My repository: GitHub - jacklemasters/tech-blog: A CMS style blog similar to a Wordpress site, where developers can publish their blog posts and comment on other posts as well. Following the MVC paradigm, using handlebars, and sequelize.

The app works locally on my machine, but I cannot seem to figure out why it will not work on Heroku. I have attempted completely moving the code, a new repository, nothing seems to help.
Here are the error logs I am receiving from Heroku:

Can you look at the log file that was printed out?

It could be a package issue, as in they didnt get installed on the heroku server you made.

Also, you have used dotenv in your packages and your server file but its not imported anywhere, and you are using process.env to initialise your server.

Could be one of the two above, if not let me know, I will look into the code again!

Have you defined your config vars in the terminal?

heroku config:set <key=value>
