'NoneType' object has no attribute 'send' when working with discord for python

I want to write a bot message to discord without command. But I got a problem when I run the code. The error says: 'NoneType' object has no attribute 'send'

Traceback (most recent call last): File "D:/Development/Code Python/Bot Discord/discord-testbot.py", line 18, in my_background_task await channel.send(channel, 'New')
AttributeError: 'NoneType' object has no attribute 'send'

import discord
client = discord.Client()

@client.event
async def on_ready():
    print('Bot is ready')
async def my_background_task():
    
    await client.wait_until_ready()
    await channel.send(channel, 'Bot say')
client.loop.create_task(my_background_task())
client.run(tokenBot)

If I remove line channel = client.get_channel(574514361394266125), then it raises another error, saying the name 'channel' is not defined.

Disclaimer: I just found this question today. I know it is already solved, but I thought I may leave my answer for future use or for other users.

This is a solution I have just for sending direct messages (in my case):

# DM message
@client.command(aliases=["dm"])
@commands.has_permissions(administrator=True)
async def _dm_(ctx, content, user_id):
    # Variables
    user = client.get_user(int(user_id))
    msg = "Sending to DM!"

    # Process
    await ctx.send(msg)
    print(msg)
    await user.send(content)

In this case, my issue initially was filling in user_id through discord as a string. Now, it takes it in as a string and then converts the ID to an integer.

It works for me. It seems that you're calling client.get_channel(id) before your client.wait_until_ready() (you've sent the edited code so I cannot guarantee it).

This code works fine for me :

async def background():
   await client.wait_until_ready()
   channel = client.get_channel(int(MY_CHANNEL))
   await channel.send("Test")

client.loop.create_task(background())

Create background tasks properly :

Since the discord.py v1.1 you can declare and manage your background task easier and safer.

This is how we do in a cog : 

import discord
from discord.ext import tasks, commands

class OnReady_Message(commands.Cog):
   def __init__(self, client):
      self.client = client
      self.send_onready_message.start()

   def cog_unload(self):
      self.send_onready_message.close()
      return

   # task
   @tasks.loop(count = 1)  # do it only one time
   async def send_onready_message(self):
      channel = self.client.get_channel(int(MY_CHANNEL))
      await channel.send("Test")

   @send_onready_message.before_loop  # wait for the client before starting the task
   async def before_send(self):
      await self.client.wait_until_ready()

      return

   @send_onready_message.after_loop  # destroy the task once it's done
   async def after_send(self):
      self.send_onready_message.close()

      return

Finally to run the task send_onready_message() we can create a Task_runner() object or simply create in instance of the task.

Task runner :

This will allow you run all your tasks easily :

# importing the tasks
from cogs.tasks.on_ready_task import OnReady_Message

class Task_runner:
   def __init__(self, client)
      self.client = client

   def run_tasks(self):
      OnReady_Message(self.client)

      return

In your main file :

import discord
from discord.ext import commands
from cogs.tasks.task_runner import Task_runner

client = commands.Bot(command_prefix = PREFIX)

runner = Task_runner(client)
runner.run_tasks()

client.run(token)

Without Task_runner :

Without the Task_runner() we have :

import discord
from discord.ext import commands
from cogs.tasks.on_ready_task import OnReady_Message

client = commands.Bot(command_prefix = PREFIX)

OnReady_Message(client)

client.run(TOKEN)

Updating discord.py :

The example above can only work if your discord.py version is up to date.

To know if it is, you can run in your terminal :

>>> import discord
>>> discord.__version__
'1.2.3'

If your version is older, you can update it by using this command in your terminal :

pip install discord.py --upgrade

Hope it helped !
