python - Discord.py error: TypeError: __new__() got an unexpected keyword argument 'deny_new'

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.

TypeError: __new__() got an unexpected keyword argument 'deny_new'

I tried it with a different file and bot and I got the same results, this is like a problem with discord.py. 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 1

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.
