Help needed with Discord bot throwing RuntimeError

I’m working on a Discord bot that’s designed to fetch and post the public IP of my Minecraft server to a specific channel. However, I keep encountering a RuntimeError related to asyncio.run().

Here’s a simplified version of the code I’m using:

import discord
from discord.ext import commands

TOKEN = 'my_secret_token'

bot = commands.Bot(command_prefix='!')

@bot.command()
async def post_ip():
    ip = get_ip()  # Assume this function exists
    channel = bot.get_channel(some_channel_id)
    await channel.send(f'Server IP: {ip}')

bot.run(TOKEN)

I’ve attempted running the bot using both client.run() and bot.run() with the token declared at the top, yet the error still occurs. Any suggestions on what might be causing this issue and how I can resolve it? I’m relatively new to Discord bot development, so I might be overlooking something obvious.

I’ve run into this exact problem before while working on my own Discord bot. The issue might be related to how you’re handling the event loop. Instead of using bot.run(TOKEN), try this approach:

import asyncio

async def start_bot():
await bot.start(TOKEN)

asyncio.run(start_bot())

This method explicitly creates and manages the event loop, which can help avoid the RuntimeError you’re experiencing. Also, make sure you’re not accidentally creating multiple event loops in your code - that’s a common pitfall.

If you’re still having trouble, double-check that you’re not mixing sync and async code inappropriately. Sometimes that can cause weird errors that are hard to track down. Good luck with your bot!

hey bud, sounds like ur having a tough time with that asyncio stuff. have u tried wrapping ur main function in an async def and using asyncio.run() to execute it? something like:

async def main():
await bot.start(TOKEN)

asyncio.run(main())

that might solve ur issue. good luck!

I’ve encountered similar issues with asyncio in Discord bots before. One thing to check is whether you’re running this script in an environment that already has an event loop, like Jupyter notebooks or certain IDEs. If so, asyncio.run() can cause conflicts.

Instead, try using asyncio.get_event_loop().run_until_complete(bot.start(TOKEN)). This approach works well in various environments without causing runtime errors.

Also, ensure you’re using the latest version of discord.py, as older versions sometimes had issues with asyncio compatibility. If problems persist, consider sharing your full error traceback – it often provides crucial details for diagnosing the root cause.
