Good day, fellow developers. I am taking a tutorial on Node.js and developed an app with Express, MongoDB atlas, etc. I used Passport-Google OAuth 2.0 for the login. Everything works well on my local machine, but it is giving me error when I deployed to Heroku. The error log is shown in the attached photo. When I run "heroku local web" on my terminal, it works fine, too. I've looked almost everywhere for solution, and tried many things; but none worked. Please, I need any help I can get to resolve this. Thank you.

Please, I apologize for the poor quality image

Lemme see the script you ran.
I hope u didn't use nodemon in production.

Not errors that made your app crash, but just point to other errors in your app.

App js line 24
should be "extended"

methodOverride not needed except in special cases,
were you just copying and pasting from the tutorial?

line 40
morgan is using dev. heroku will run natually in production, and morgan would not log anything meaningful,
better to use a custom logger or at least, morgan combined format

i can see you r doing schema validation in your models, it is way better to handle input validation at the very first layer,
so that errors are caught very early . . instead of troubling javacript all the way down the layers, only to fail a validation just before insertion into DB...
for a quick fix, a package like Joi comes to mind

middlware auth.js line 5 and co.

you dont need to an else statement, if the "if block" contains a return statement. after your if block, just write the other condition, since it will always return if the "if block is activated"

you followed the MVC pattern partially, no controllers. . .
plus you need to start learnign EcmaScript 6+, as it will make your life easier
and code easy to follow thru

and next time, pls add a sample .env file, so people can clone and run your project correctly. that was the only thing holding me back,
as i am too busy to scan the whole codebase for "process.env" annotations.

Debugging itself is an art that has to be learned. The crashalytics gave you a file where the error is contained.
I can help you but first you must help yourself.

step 1. Login to heroku bash and
step 2. "cat" that file and read the log, to understand why the error happened

Then come back and report what you discovered.

Thank you, boss, for your help. You're the real MVP. I'll like you to mentor me Node.js. I'm actually good with PHP, but still picking up on Node.js

See you solved it, great! I was kinda bogged down with work and couldn't come online.
I rechecked the codebase and see you cleaned up a bit. At least, that makes for improvement. One step at a time.

If you have free internet, i'll like you to very much watch other contents on debugging, cos when you get to working in a production environment,
you'll spend most of your time debugging "other people's errors" and those you created yourself.

As per the mentoring, we'll see how it goes. I am always bogged down with work, but if you do run into issues, just let me know. Trust me, i'll not solve them for you, i'll just tell you what to do and you'll have to solve it yourself [to learn].

Cheers.

I appreciate, boss. I'd really like you to point out some resources on debugging codes (especially YouTube videos or ebooks) if possible.

I have always known that it's better to teach one how to fish rather than giving him fish, so I would love it if you give directions on what to do just like you did above. Let me send you a PM. I don't know if your mail works, mine do.
Thank you.

Nah, that's a burner email. I guess if you use the follow button, we'll be able to exchange comms pretty effectively.
