I get the same error when I try to run the application locally
11:26:03 web.1 | var port = process.env.PORT || 5000;
11:26:03 web.1 | ^
11:26:03 web.1 | TypeError: Cannot read property 'PORT' of undefined
Does someone know what am I doing wrong?

NodeJs MongoDB and Heroku

While deploying a Node application to Heroku I'm receiving the following error message. Any ideas what might cause it?

I think you are creating mongoose connection with connect not with createConnection method that's why you are getting this error.
.createConnection() returns a Connection instance.
.connect() returns the global mongoose instance.
Then if you want to use once method then you have to use createConnection method instead of connect method
var db = mongoose.createConnection('MongoDB URL');
db.once('open', function() { ... });
