I have developed a Discord bot for my private server utilizing discord.py, and it functions flawlessly when executed locally. However, after deploying it on Heroku via GitHub, I noticed that while the bot is showing as online, it doesn’t respond to any of the commands or functions I invoke.
The deployment process seemed straightforward; I linked my GitHub repository with Heroku, and the build process completed without any issues. Yet, when I attempt to use the bot in my Discord server, there are no replies or any indication of errors—just complete silence.
I would appreciate any insights into possible configuration steps I might have overlooked during the Heroku setup. Could it involve environment variables, the setup of the Procfile, or the needs for worker dynos? I am confident the core functionality is intact since it works well in my local environment.
Had the same problem when I first deployed to Heroku. Turns out my local Python dependencies didn’t match what Heroku installed. Run pip freeze > requirements.txt to lock in the exact versions that work on your machine. Also check if your bot references any local file paths - Heroku’s filesystem is totally different. Timezone differences got me too. My scheduled tasks broke because Heroku runs on UTC while I was testing locally. Your bot might be running but silently failing on stuff that worked fine locally.
check your heroku logs first - that’ll show you what’s happening. run heroku logs --tail and watch for errors when you try commands. it’s probably crashing silently or your intents aren’t set up right in the discord dev portal.
It’s not uncommon to face such issues after deploying on Heroku. One potential culprit could be the Procfile configuration; ensure it’s specified as worker: python bot.py. This is crucial since Discord bots require a worker dyno to operate effectively. After adjusting that, remember to enable the worker dyno in Heroku’s Resources section, as it can be disabled by default. Additionally, double-check that the bot token in your environment variables matches what you have coded, as any discrepancies could lead to the bot being non-responsive.
