Why Aren't My Discord.py Bot Commands Working After Customizing on_message?

Understanding the Issue: Commands Not Functioning

When using the Discord.py library, some users encounter unexpected behavior where commands fail to execute even though the bot appears to be active. This issue can be attributed to the on_message event handler.

Fixing the Problem: Adding bot.process_commands(message)

According to the Discord.py documentation, overriding the default on_message event handler prevents additional commands from executing. To resolve this, it is necessary to include a bot.process_commands(message) line at the end of the custom on_message function.

Referencing the documentation for guidance:

Overriding the default provided on_message forbids any extra commands from running. To fix this, add a bot.process_commands(message) line at the end of your on_message.

Example Implementation:

import discord
import asyncio
from discord.ext import commands

bot = commands.Bot(command_prefix = '-')
@bot.event
async def on_ready():
    print('Logged in as')
    print(bot.user.name)
    print(bot.user.id)
    print('------')

@bot.event
async def on_message(message):
    # do some extra stuff here

    await bot.process_commands(message)

By following this guideline, you can retain the functionality of your custom on_message event handler while ensuring that commands continue to operate seamlessly.
