Common Errors

Running into issues? This page covers the most common errors you’ll encounter when hosting a Discord bot, from Pterodactyl panel problems to runtime crashes.

Pterodactyl Panel Errors

Server Won’t Start / Stuck on “Starting”

Symptoms: The server stays on “Starting” and never transitions to “Running”, or it immediately goes back to “Offline”. Causes & Fixes:
The startup command doesn’t match your actual entry file. Go to Settings > Startup and verify the command points to the correct file:
  • If your file is bot.py, the command should be python bot.py
  • If your file is index.js, the command should be node index.js
A mismatch like python main.py when your file is named bot.py will cause the server to fail silently.
Your entry file is inside a subfolder (e.g., my-bot/bot.py) instead of at the root of the file manager. The server looks for your file at the root level. See File Structure for how to fix this.
Your bot requires packages that aren’t installed. Make sure you have:
  • Python: A requirements.txt at the root with all your packages listed
  • JavaScript: A package.json at the root with dependencies defined
Check the console output for lines like ModuleNotFoundError or Cannot find module — these confirm missing dependencies.

”Failed to Start” or Exit Code Errors

Common exit codes:
Exit CodeMeaningLikely Fix
1General error / uncaught exceptionCheck console for the error traceback — usually a code bug or missing config
127Command not foundYour startup command references a binary that doesn’t exist (e.g., python3 instead of python)
137Out of memory (OOM killed)Your bot is using more RAM than your plan allows — optimize memory usage or upgrade
139Segmentation faultRare — usually caused by a native dependency issue. Try reinstalling dependencies

Console Shows No Output

If the console is completely blank after starting:
  • Your startup command may be wrong — double-check the filename
  • Your bot might be crashing before it can print anything — add a simple print("Starting...") or console.log("Starting...") as the very first line of your entry file to verify it’s being executed

File Manager Won’t Upload

  • File too large: The panel has upload size limits. For large uploads, use SFTP instead. See Uploading Files.
  • Permission error: Try refreshing the page and re-uploading. If it persists, open a support ticket.

Python Errors

ModuleNotFoundError: No module named 'xyz'

Your bot is trying to import a package that isn’t installed. Fix: Add the missing package to your requirements.txt file and restart the server:
discord.py
python-dotenv
aiohttp
Make sure requirements.txt is at the root level of your server files.

SyntaxError: invalid syntax

Usually means you’re running Python 2 syntax on a Python 3 server, or there’s a genuine typo in your code. Fix: Test your code locally with python bot.py to find the exact line causing the issue.

discord.errors.LoginFailure: Improper token has been passed

Your bot token is invalid, missing, or incorrectly loaded. Fix:
  • Verify your token in the Discord Developer Portal
  • If using a .env file, make sure there are no extra spaces or quotes around the token
  • If using a config file, check that your code reads the correct key
  • Try resetting your token in the Developer Portal and updating it on the server

discord.errors.PrivilegedIntentsError

Your bot needs privileged intents (like Message Content) that aren’t enabled. Fix: Go to the Discord Developer Portal > your app > Bot tab > enable the required intents (Message Content, Server Members, Presence).

JavaScript / Node.js Errors

Error: Cannot find module 'xyz'

A required npm package is missing. Fix: Make sure your package.json includes all dependencies and is at the root level. The server installs packages from package.json on startup. If a package is missing from package.json, add it:
{
  "dependencies": {
    "discord.js": "^14.14.1",
    "dotenv": "^16.3.1"
  }
}

Error [TOKEN_INVALID]: An invalid token was provided

Same as the Python token error — your token is wrong or not being loaded. Fix: Check your token source (.env, config.json, or environment variable) and verify it matches the token from the Discord Developer Portal.

TypeError: Cannot read properties of undefined

Your code is trying to access a property on something that doesn’t exist yet. Common causes:
  • Trying to use client.user before the bot is ready — wrap it in a ready event
  • Missing or malformed config values
  • API responses returning unexpected data

EADDRINUSE: address already in use

Something is already listening on the port your bot is trying to use. This usually happens if your bot runs a web server alongside the Discord connection. Fix: Use the port assigned by the panel via the environment variable (typically process.env.SERVER_PORT or process.env.PORT) instead of hardcoding a port number.

General Issues

Bot Goes Offline After a Few Minutes

  • No keep-alive mechanism: If you’re using a free-tier database or external API that disconnects after inactivity, make sure your code handles reconnection
  • Unhandled promise rejection (JS) or unhandled exception (Python): Add global error handlers so your bot doesn’t crash on unexpected errors
Python:
@bot.event
async def on_error(event, *args, **kwargs):
    print(f"Error in {event}")
JavaScript:
process.on('unhandledRejection', (error) => {
  console.error('Unhandled promise rejection:', error);
});

Bot Runs Out of Memory

If your bot gets killed with exit code 137:
  • Avoid storing large amounts of data in memory (use a database instead)
  • Check for memory leaks — objects that grow over time without being cleaned up
  • Consider upgrading to a plan with more RAM

Bot Is Online but Not Responding to Commands

  • Missing Message Content Intent: If using message-based commands (not slash commands), enable the Message Content intent in the Developer Portal
  • Wrong prefix: Double-check your command prefix matches what you’re typing
  • Slash commands not synced: If using slash commands, make sure you’ve synced them with Discord (this is a one-time step after adding new commands)

Still Stuck?

If none of the above fixes your issue:
  • Check the console carefully for the full error message and traceback
  • Search the error in your bot library’s documentation or GitHub issues
  • Open a support ticket in our Discord server — include the full console output and a description of what you’ve already tried
