Hey everyone! I’m trying to get n8n up and running on Heroku, but I’m hitting a wall. I’ve set up my Heroku app and tried different Procfile configs, but nothing’s working. When I visit the app URL, all I see is “There’s nothing here, yet.”
I’ve done a bunch of stuff like:
- Changed the Procfile command
- Checked my package.json
- Looked at Heroku logs
- Restarted dynos
- Tested n8n locally (it works fine there)
But I’m still stuck. The main error I’m seeing is /bin/sh: 1: n8n: not found. I’m not a coder, so I’m pretty lost.
Can anyone walk me through how to fix this, step by step? I’d really appreciate some beginner-friendly advice on getting n8n to play nice with Heroku. Thanks in advance for any help!
hey there zoestar42! i’ve seen similar issues. sounds like n8n isn’t installed properly. try updating ur procfile to say
web: npm install n8n && n8n start
and add n8n to ur package.json dependencies. if issues persist, ping me for more help!
I’ve encountered this problem before when deploying n8n on Heroku. The issue often stems from incorrect Node.js version specification. First, ensure your package.json includes the correct engine version:
“engines”: {
“node”: “14.x”
}
Then, in your Procfile, try using the following command:
web: NODE_OPTIONS=‘–max_old_space_size=4096’ npm run start
Lastly, double-check that you’ve set the necessary environment variables in your Heroku app settings, particularly DATABASE_URL and WEBHOOK_URL. These steps should resolve the ‘n8n: not found’ error and get your instance running smoothly on Heroku.
I’ve gone through the n8n-Heroku deployment process recently, and it can be tricky. One thing that helped me was using the Heroku CLI for troubleshooting. After you’ve made the changes suggested by others, try running ‘heroku logs --tail’ in your terminal. This gives you real-time logs as your app tries to start.
Another issue I encountered was related to the Heroku stack. Make sure you’re using the ‘heroku-20’ stack, as some older stacks can cause compatibility issues with n8n. You can check this in your app settings on the Heroku dashboard.
Lastly, if you’re still stuck, consider temporarily switching to a ‘worker’ dyno instead of a ‘web’ dyno. This bypasses some of Heroku’s web process expectations and might help isolate the issue. Good luck with your deployment!
