We’re having issues starting the app, which was developed using Heroku (and was working perfectly over a period of months). We did not alter or install any files (we just added information). Sometimes we encounter this error in Heroku logs

  1. Here’s what I did:

    1. I restarted the Heroku instance and it worked fine

    2. I deleted all the project files

    3. I exported them (before making any edits) to a new Java 8 project, which is where I’m currently in development

    4. It worked just fine on Heroku, but when I deploy my code to my local machine, it’s giving me this error: “Could not find class LoadingController”. It doesn’t seem like there is anything special about its dependencies or anything. Any idea what’s going on? Also, how do you export a project from Heroku? How do you install Java?

  2. In my case my app crashed because I was hard setting the PORT, instead of using the port that heroku dinamicaly sets, which can be accessed with process.env.PORT

    app.listen(process.env.PORT || 3000, function(){
console.log("Express server listening on port %d in %s mode", this.address().port, app.settings.env);
});
