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.

Answer 2

An alternate option, if you are stuck with an older version of discord.py and would rather not have to update 10k+ lines of code right now, is the following quick and dirty patch I came up with based on this commit:

(note: this is diff'd against discord.py 0.16.7. It may be slightly different depending on what version of discord.py you're running.)

I must stress that this is a hack at best, and there are no guarantees as to how long this will continue to work. Furthermore, there are no guarantees that Discord won't suddenly introduce some other random API change that will break older discord.py in new and interesting ways. You (like I) should really update your code to comply with the newer discord.py. I only present this workaround as I suspect you are in the same situation as me (having things suddenly break and needing to get things back up and running RIGHT NOW but not having the time to quickly update 10k+ lines of code to fix this.

Answer 3

I just had this issue and just now fixed it, and here is what I did (this worked for my laptop running Windows):

pip uninstall discord.py
pip install discord.py
py -3 -m pip install -U discord.py

I also am running a discord bot on a Raspberry Pi and this is how I fixed it:

pip uninstall discord.py
pip install discord.py
python3 -m pip install -U discord.py
