Question: Yesterday, my code was perfectly fine. Everything was running... and it was going great. All of a sudden, this error: TypeError: __new__() got an unexpected keyword argument 'deny_new'  pops up in my PyCharm console. I've looked it up on the internet but I've only found a similiar questions with zero answers to it. I hope the stackoverflow community will be able to help me. I did not change my code, all I did was, I tried to host my bot on heroku, and it did not go well. And after my first few attempts, I gave up. But, I found out my bot started going crazy and I couldn't run it anymore :<. Has anyone else experienced this and know how to fix it? UPDATE I just found out that for some reason, it only works on my test server but not any other servers.

This is literally my entire code import discord import random from discord.ext import commands import asyncio client = commands.Bot(command_prefix='{') client.remove_command('help') @client.event async def on_ready(): print("Signed in") @client.command() async def dm(ctx): await ctx.author.send("What up chump?") client.run('TOKEN') 

Answer: Discord pushed a new change that changes the overwrites object. Just reinstall the latest version of Discord.py python3 -m pip install -U discord.py  That's it.
