#`RuntimeError: Session is closed` when using `bot.close()`

Hi, for some reason I get this error when I stop my bot using bot.close(). I tried this on a clean bot too and it still persists. Using CTRL+C does not have this issue. Anyone have an idea what might cause this? Can you reproduce this? I'm on Python 3.12.4 and pycord 2.7.1.

bot = discord.Bot(intents=discord.Intents.all(), debug_guilds=[...])

@bot.command()
@discord.default_permissions(administrator=True)
async def stop(ctx: discord.ApplicationContext):
    """Stop the bot."""
    await ctx.respond("Stopping the bot...", ephemeral=True)
    await bot.close()

bot.run(os.getenv("BOT_TOKEN"))

Traceback (most recent call last):

RuntimeError: Session is closed when using bot.close()

try using sys.exit()

#

but I need to run some code after bot.run()...

#

like cleanup and stuff

#

using sys.exit() would just kill the bot, no?

#

like

bot = discord.Bot(intents=discord.Intents.all(), debug_guilds=[717770840221024422])

@bot.command()
@discord.default_permissions(administrator=True)
async def stop(ctx: discord.ApplicationContext):
    """Stop the bot."""
    await ctx.respond("Stopping the bot...", ephemeral=True)
    await bot.close()

dotenv.load_dotenv()
bot.run(os.getenv("BOT_TOKEN"))

bot.cleanup()
print("See you soon!")
wraith frost
# 
try:
    bot.run(...)
except RuntimeError: # or some other error
    cleanup()
    raise

#

Yeah ok, sure I can catch it but that doesn't solve the underlying problem, does it? It should not throw this error in the first place. Can you reproduce the error?

#

I want to make sure it's not just me, before opening an Issue on github

wraith frost
#

When using bot.close, cleanup steps aren't executed

#

bot.run uses those

#

However something you could try is this pull request:

#

So just raising a KeyboardInterrupt is better than using bot.close() ig xD

We might change this in the future but we need to refactor the asyncio setup as shown above first

Alright, thanks for the help 🙂
