Heroku NodeJS - Error: Cannot find module './prod.json' - json

First time pushing this app to heroku (and first time doing a NodeJS API), and when the app tries to start, I get this error in heroku's logs. It works fine in dev - what am I missing?
I have a file: config/prod.json
And in package.json
"scripts": {
"start": "export NODE_ENV=prod && nodemon ./index.js",
"windev": "set NODE_ENV=dev && nodemon ./index.js",
"dev": "export NODE_ENV=dev && nodemon ./index.js",
"prod": "export NODE_ENV=prod && nodemon ./index.js",
"test": "echo \"Error: no test specified\" && exit 1"
},
Full output:

'Node Api using mysql' deployed on heroku crashes after some time Interval

I have created a Node API using MySQL and deployed it on Heroku. But after every 20-25 minutes it shows 'Application error' and I have to do 'Heroku restart' again to fetch data from API. My API calls work fine when runs on localhost:port_no

I assume that you did bind your port to the environment variable $PORT which was supplied by Heroku. I assume that port is the 5967. Your program is trying to access 3306. You probably defined this port somewhere. This is on Heroku not possible.
Heroku only allows you to bind to a single port with the port number decided by Heroku.

You got an Error. Because your server tries to connect a 3306 PORT
But in your server Listening to a port 5967. simple change a PORT Number in own code .env file. Define a like
E.g.HOST=5967 in the .env file

app not deploying to heroku

I am having a problem with deploying my app on heroku. I am stuck and cannot find the answer. I have went through the heroku troubleshooting and deployment procedures. I have been trying for 3 days. I have rewritten my env file numerous times and every time I do, it doesn't work on localhost. I have MONGOD and NODEMON running. I reverted back to the original and it is working. But still will not deploy on heroku. Thanks in advance.
Here is what my env.js looks like
module.exports = {
db: process.env.MONGODB_URI || 'mongodb://localhost/sailcast',
port: process.env.PORT || 3000
}

That looks fine. One thing that came up to my mind is that if your file called app.js or index.js since it is an error with npm start? Maybe you made a typo.
Another thing that came up to my mind is that, if you set up the environment database value from the heroku. Since, I cannot see your whole heroku logs, it is another possibility

After stop GULP with CMD+Z got an error: ✗ ... Uhoh. Got error %s ... listen EADDRINUSE

I was working as usual until I stop the server by mistake by playing CMD+Z and got this very big error on my terminal:

The examples in the docs did not tell me anything, do you have a clue?
I already nvm use 0.10.X and nothing, restart computer and nothing. Also I checked my code and everything is correct.

just restart your console, I just went thru all of this already
