Heroku error code=H10 - node.js

I keep getting error code=H10 randomly when I start my Heroku app. Sometimes the app starts, sometimes it doesn't.
My app is built with NodeJS, Express, MySQL and JawsDB.
Here's the details in my app's log:
2017-11-26T15:21:36.906937+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=<my app name>.herokuapp.com request_id=4c63d70d-f081-44a5-b4fe-f0992116ba79 fwd="108.28.184.177" dyno= connect= service= status=503 bytes= protocol=https
2017-11-26T15:21:36.954063+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" host=<my app name>.herokuapp.com request_id=e42d6293-512f-4ea1-ba35-403f44e4fd9a fwd="108.28.184.177" dyno= connect= service= status=503 bytes= protocol=https
I've looked online and added favicon.ico in my public folder. Nothing changes. I've had this problem before with my previous app and I ran heroku restart and it works for that one, but doesn't for this one.

Application error while opening URL for app deployed in Heroku

I have deployed my webpage on Heroku, with MongoAtlas for hosting database. The site has been deployed successfully, but on opening the URL it shows the following error.
An error occurred in the application and your page could not be
served. If you are the application owner, check your logs for details.
You can do this from the Heroku CLI with the command heroku logs
--tail
The logs show this

Node/React app won't deploy on Heroku

I've tried everything I can think of and exhausted google searches. I've already ruled out the most common problems (ex: not using process.env.PORT in app.listen).
Here are the heroku logs:

And here is the server.js file
Any help would be greatly appreciated!
It turns out the log files weren't showing all the errors for some reason -- there was a typo in one of my imports. :)

Heroku app is getting crashed

I recently learned node.js and wanted to deploy my project, which I did on Heroku. However, Heroku is giving me the error messages copied below. Though I have logged the error, I am still not able to figure out the solution.

Here is the error:
An error occurred in the application and your page could not be served. Please try again in a few moments.
If you are the application owner, check your logs for details.
The node.js server is crashing upon HTTP GET request on route /. This isn't a platform error, but a code error (likely your index.js file). You will want to check the code for error between the lines:
app.get('/', function(req, res) {
//likely some syntax error here
}
I highly recommend running the app on your local machine using command such as: node index.js to see what part of your HTTP GET code is causing the error. The CLI will give a specific line number on where the error is being caused.
Heroku Local is also a great tool for testing your app before deploying it to heroku.
