Heroku is not letting me start the application as it stays on for a few seconds, and then this happens:

```
2020-04-07T23:11:35.586817+00:00 heroku[web.1]: State changed from starting to crashed
2020-04-07T23:11:35.597942+00:00 heroku[web.1]: State changed from crashed to starting

```

After that, Heroku restarts the application, and the above code is displayed one more time (this time there is no restart, just a crash).

```
2020-04-07T23:12:38.593514+00:00 heroku[web.1]: State changed from starting to crashed

```

I've searched for problems in my code, and I could not found any, so I deleted everything, and make my main file `core.js` a single discord bot, that just send an embed message with a title:

```js
const { Client, MessageEmbed } = require('discord.js')
const client = new Client()
let channel = null

client.on('ready', () => {
  console.log(`bot ${client.user.tag} running`)
  channel = client.channels.cache.find(ch => /generic_channel_name/.test(ch.name))

  const embed = new MessageEmbed()
    .setTitle('Commom title')
    .setColor('#ffff00');
    channel.send(embed)
})

client.login(config.token)

```

Even a single setInterval causes the Heroku to crash the app:

```js
setInterval(() => {
  console.log('Testing')
}, 3000)

```

I really tried lots of things, but the only thing I did that didn't crash was a simple for loop from 0 to 100.000

Can someone help me?
