Hey everyone, I’m having a hard time getting my Discord bot to work on Heroku. It runs fine on my computer, but Heroku is giving me headaches.
When I try to start it up, I get this error:
2018-08-29T13:57:58.295022+00:00 app[web.1]: (node:4) ExperimentalWarning:
The http2 module is an experimental API.
2018-08-29T13:57:58.732365+00:00 app[web.1]: Bot is ready!
2018-08-29T13:58:55.278962+00:00 heroku[web.1]: Error R10 (Boot timeout) ->
Web process failed to bind to $PORT within 60 seconds of launch
I tried adding this code to fix it:
const SERVER_PORT = process.env.PORT || 3000;
server.listen(SERVER_PORT, () => {
console.log(`Server running on port ${SERVER_PORT}`);
});
But now I’m getting a new error:
ReferenceError: server is not defined
at Object.<anonymous> (/app/bot.js:8:1)
Any ideas on how to get this working? I’m pretty stumped.
I’ve been down this road before, and it can be frustrating. The issue you’re facing is likely due to Heroku expecting a web process while your bot is running on a worker process. In my experience, you can resolve this by updating your Procfile so that it includes only the worker process (for example: worker: node bot.js) and by removing any references to a web process. Also, remove any server code that’s unnecessary for a Discord bot. Finally, double-check that you’re using environment variables for your sensitive data, such as your bot token, and ensure all dependencies are correctly listed in your package.json.
yo, i had similar issues. try removing that server code - discord bots don’t need it. change ur Procfile to ‘worker: node bot.js’ instead. make sure ur using environment vars for sensitive stuff like bot token. check ur package.json has all the right dependencies listed. that should sort it out for ya!
From what I’ve seen, the main issue here is a mismatch between Heroku’s expectations and your bot’s setup. Heroku is looking for a web process, but Discord bots typically run as worker processes. To fix this, you should modify your Procfile to specify a worker dyno instead of a web dyno. Something like ‘worker: node bot.js’ should do the trick.
As for the server code you added, that’s not necessary for a Discord bot. Remove that entirely. Discord bots don’t need to listen on a port. They communicate directly with Discord’s servers via WebSocket.
Lastly, make sure all your environment variables are set correctly in Heroku’s config vars. This includes your bot token and any other sensitive information. Double-check your package.json to ensure all dependencies are listed correctly too. These steps should resolve your deployment issues.
