Heroku app is getting crashed - node.js

Question

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 are the logs:

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.

Answer 1

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.
