node.js - Getting H13 Error when visiting deployed Heroku Site

Question

I am able to deploy my heroku app, but when I visit the site I get an "Application Error"

I check the logs and I get this error.

I am really not sure what is causing the error,

Thank you

I found what the problem was, I was not connecting the Atlas DB properly.

I found this video and it helped. https://www.youtube.com/watch?v=WVxG1Smf92o&ab_channel=Kristian
