Discord.py - Asyncio Timeout not working properly - python-3.x

Question

Expected output and what my code for it is:
My bot is supposed to send a message, and then check if the user who sent the command reacted on that message with :arrow_left:, :arrow_right:, or :wastebasket: and if they did, it is supposed to change the "page" of the message. That part works fine, but I also want the message to timeout after 7 seconds of inactivity.
embed = await self.get_member_list(ctx, member, page)
msg = await ctx.send(embed=embed)
reactions = ["⬅️", "➡️", "🗑️"]
for x in r:
await msg.add_reaction(x)
await asyncio.sleep(.35)
def check(payload):
return str(payload.emoji) in reactions
done = False
page = 1
while not done:
try:
pending_tasks = [self.bot.wait_for('raw_reaction_add', timeout=7.0, check=check),
self.bot.wait_for('raw_reaction_remove', timeout=7.0, check=check)]
done_tasks, pending_tasks = await asyncio.wait(pending_tasks, return_when=asyncio.FIRST_COMPLETED)
for task in done_tasks: payload = await task
user = await commands.MemberConverter().convert(ctx, str(payload.user_id))
except asyncio.TimeoutError:
done = True
return
else:
if user == ctx.author:
if str(payload.emoji) == "🗑️":
return await msg.delete(delay=0)
if str(payload.emoji) == "⬅️":
if page == 1:
page = total_pages
else:
page -= 1
if str(payload.emoji) == "➡️":
if page == total_pages:
page = 1
else:
page += 1
await msg.edit(embed=await self.get_member_list(ctx, member, page)) #
However, I am facing the problem "Task exception was never retrieved" after running the code above.
Actual results:
Task exception was never retrieved
future: <Task finished name='Task-58' coro=<wait_for() done, defined at C:\Users\AppData\Local\Programs\Python\Python38\lib\asyncio\tasks.py:434> exception=TimeoutError()>
Traceback (most recent call last):
File "C:\Users\AppData\Local\Programs\Python\Python38\lib\asyncio\tasks.py", line 501, in wait_for
raise exceptions.TimeoutError()
asyncio.exceptions.TimeoutError
The problem:
Whenever 7 seconds of inactivity passes and it is supposed to timeout I get an error. I have tried to fix this by running asyncio.gather() but I am unfamiliar with asyncio and I am unsure how to use it properly.
done_tasks, pending_tasks = await asyncio.wait(pending_tasks, return_when=asyncio.FIRST_COMPLETED)
await asyncio.gather('raw_reaction_add', 'raw_reaction_remove', return_exceptions=True)
I have tried:
Checking for typos
Running except Exception and except asyncio.exceptions.TimeoutError instead of except asyncio.TimeoutError
Contemplating my sanity
Reading the asyncio documentation, specifically on asyncio.wait()
Making sure that my bot has all the permissions and intents it needs in discord
Using self.bot.wait_for() with raw_reaction_add and raw_reaction_remove inside of a tuple instead of asyncio.wait()

I ended up getting rid of the error message by doing this:
First I moved the timeout from bot.wait_for() to asyncio.wait()
pending_tasks = [self.bot.wait_for('raw_reaction_add', check=check),
self.bot.wait_for('raw_reaction_remove', check=check)]
done_tasks, pending_tasks = await asyncio.wait(pending_tasks, timeout=7.0, return_when=asyncio.FIRST_COMPLETED)
Then I got the payload from a pop instead of awaiting task
payload = done_tasks.pop().result()
Now after 7 seconds of inactivity it tries to pop from an empty set and raises a KeyError which I can catch using except KeyError:
