node.jsherokuheroku-api

Heroku error: heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/"?

I'm trying to deploy very simple Nodejs API on Heroku, but I can't seem to figure out why it keeps on giving me this error. The app runs just fine on local server, even with heroku local web. My app is listening on app.listen( process.env.PORT || 5500 );.

Here is my error when I heroku logs --tail.

What am I missing? I've tried many things surfing on Stackoverflow but nothing helped yet :(

Solution

  • Use the following code to make a connection-

    mongoose.connect(uri, {
      useNewUrlParser: true,
      useCreateIndex: true,
      useUnifiedTopology: true
    }).then(res=>{
            console.log("DB Connected!")
    }).catch(err => {
      console.log(Error, err.message);
    })

    If using the above code-
    You need to whitelist the heroku IP address b going to MongoDB Atlas.
    Ip Addres to be added is- '0.0.0.0/0'
