production.json probably has an error, check if it is a valid JSON code

Someone suggested Heroku. I connected it to my github. After deploying it tells me application error see below:

So on deploying my app to Heroku, it has started crashing. Unfortunately the log doesn't help as there is no detail.
I have tried restarting the app & it doesn't help.
The env variables are entered
The builpack is set to heroku-nodejs
The above 3 are what I found on web. Thanks for all the help.
Here is the log from Heroku

Resolved this.
I had a wrong path for one of dependencies. Rectifying the right path is all that was needed.
I am trying to host my app on heroku but everytime it is showing this
I don't know what to do localhost is working fine.
i have both 3000||PORT in app.js
app.listen(3000 || process.env.PORT, function() {
console.log("server started");
});

Can you change your listener to something like this because I guess heroku doesn't allow you to assign listening ports but provides them dynamically. In your case 3000 || process.env.PORT it always return PORT 3000.
app.listen(process.env.PORT || 3000, function() {
console.log("server started");
});
I am creating a very simple Heroku NodeJS server and it is throwing the following error when I load the page:
Failed to load resource: the server responded with a status of 503 (Service Unavailable)
The code for the index.js file:
const express = require('express');
const app = express();
app.get('/', (request, res) => {
res.send('Conneccteedd!!')
}
)
app.get('/something', (request, res) => {
res.send('somethingg!!')
}
)
app.listen(3000, () => console.log('Example app listening on post 3000!'))
When I run heroku logs, I get this:

From comments:
Why port 3000? How does Heroku know to proxy traffic to that port?
const PORT = process.env.PORT || 3000;
app.listen(PORT);
I have been having difficulties deploying on heroku. Followed the deploying a node js app on heroku guide but still keep getting an application error. any idea why please? here is my heroku logs

From your logs, it looks like you are NOT binding to the right port.
I'm going to assume that your Express.js app looks something like this:
app.listen(3000);
This line of code tells Express.js to start running a web server on port 3000. This is fine when you're writing code on your laptop, but when you deploy code to Heroku, Heroku will assign you a RANDOM port number that you MUST bind to.
So, to fix your problem, you should rewrite the above line of code to look like this:
app.listen(process.env.PORT || 3000);
This will tell your app to run on the correct Heroku port, but fall back to port 3000 when doing development on your local laptop =) This is the best of both worlds.
Hope this helps!
