also the script that i added:https://help.heroku.com/P1AVPANS/why-is-my-node-js-app-crashing-with-an-r10-error

const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
    console.log(`Our app is running on port ${ PORT }`);
});

Hmm...it seems that the error is that app is not defined.

I am assuming you are using the JS Express library, so make sure the Express library was correctly installed. Double check if you are importing it correctly into your program, and make sure to define const app = express();
