client.fetch_channel() returns AttributeError: '_MissingSentinel' object has no attribute 'is_set'

I want to send a message to a specific channel. I get the channel, but when I try to send a message it makes this error:
Traceback (most recent call last):
File "C:\Users\nikit\PycharmProjects\Phantom_Shop\discord\ui\view.py", line 425, in _scheduled_task
await item.callback(interaction)
File "C:\Users\nikit\PycharmProjects\Phantom_Shop\temporary_classes.py", line 200, in buy_callback
await channel.send("Test")
AttributeError: 'NoneType' object has no attribute 'send'
I am doing this in a separate file(specifically in a button callback in a View)
Here's the part of separate file that is used:
from temporary_bot import client
channel = client.get_channel(channel_id)
await channel.send("Test")
and here's the main file:
client = discord.Client(intents=intents)
tree = app_commands.CommandTree(client)
channel = client.get_channel(***)
#client.event
async def on_ready():
await tree.sync()
print('We have logged in as {0.user} bot'.format(client))
#tree.command(name = "start", description = "Start the bot")
async def first_command(interaction):
view = Menu_View()
view.add_item(url)
keys = data["profiles"]
if f"{interaction.user}" in keys:
print("Account already in database")
else:
data["profiles"][f"{interaction.user}"] = {}
data["profiles"][f"{interaction.user}"]["balance"] = 0
print("This is bullshit")
data["profiles"][f"{interaction.user}"]["spent"] = 0
data["profiles"][f"{interaction.user}"]["bought_product"] = 0
with open("profiles.json", "w") as file:
json.dump(data, file)
menu = make_menu(interaction.user.avatar)
await interaction.response.send_message(embed=menu, view=view)
if __name__ == "__main__":
client.run(TOKEN)
I tried creating the variable in the main file but it made the same error.
I use a number as my channel id and I tried it with other channels, same thing.

You're trying to get the channel before the bot is started. Try setting it in on_ready:
global channel
channel = client.get_channel(1062092063128166571)
Or better just get it in your callback
channel = client.get_channel(1062092063128166571)
await channel.send("Test")
If you want to save it in a global variable, it's better to use constant-like variable with id
CHANNEL_ID = 1062092063128166571
# Somewhere in a callback...
channel = client.get_channel(CHANNEL_ID)
await channel.send("Test")

I just fixed the problem by creating the channel variable in a third file, then editing it in the on_ready function, and finally importing it in the classes file

playlist load take too much time and my bot get disconnected (yt-dl and discord.py)

I have a strange problem with my bot made with discord.py and youtube-dl, when I load a small playlist the bot works perfectly, when instead I load a long playlist, like 100 songs, the bot has to download them all and then start them , I think the time used to download the songs is seen as inactivity and then the bot disconnects, however it does not disconnect from the channel on discord, only code side it disconnects, how can i solve?

the bot has to download them all and then start them
1. Don't download the tracks, stream the raw URL (The argument for the command line is --get-url) (You say you are downloading but the code does not do that it extracts raw URL?)
2. I've noticed that YT-DL seems to be slower now. I use a new library called YT-DLP It is way faster than YT-DL and I am able to parse through an entire playlist of 200 songs in less than 5 seconds. (not downloading them of course.)
3. Instead of parsing a whole playlist and extracting raw URLs all at once, extract just the regular URL then when it's time for that song to play from the queue, extract the raw URL and then, play it.

So, I'm making a reaction role command and it keeps giving me the same error,I have enabled intents. members, everything I need but still it gives me the same error.I dont know why its giving me this error,maybe its a bug or somethng??.

The member attribute isn't available in the on_raw_reaction_remove event.
What you can do instead is
Figure out whether to give or remove the role both in on_raw_reaction_add, when a user reacts check if they have the role, if not add if they do then remove the role. Then remove their reaction from the message. This would essentially be a toggle reaction role.
OR
Use the payload.user_id and fetch the member using await fetch_user(user_id).

Thanks in advance,

This post helps you.
The reason program couldn't stop is that sub threads continue to run even if main thread catches an exception and stop. Note that asyncio is implemented by thread (I pursued codes). There are two kinds of thread in Python, normal thread and daemon thread. The former continues to run if parent thread dies, the latter stops. asyncio is implemented with the former, therefore such this problem happens.

discord bot autorole -- in _run_event yield from getattr(self, event)(*args, **kwargs)

I am new to Python and have some issues with my Discord Bot which I do not get fixed. The bot should automatically assign roles to users who join the server for the first time. I can set up autorole successfully. But when a user joins the server, the following error message appears in the console.
