Race condition in InteractionResponse

[Mihitoko]

Summary

There is a race condition in InteractionResponse

Reproduction Steps

Running two task that will send a response to a Interaction will end in unexpected error.
Second Task will Raise NotFound Exception instead of InteractionResponded error.
This is due to a race condition in the libarry.

And because of this ApplicationContext.respond is also broken.

Minimal Reproducible Code

import asyncio

import discord.ext.commands

bot = discord.ext.commands.Bot()


@bot.slash_command(guild_ids=[...])
async def foo(ctx):
    async def respond():
        await ctx.respond("Race condition")

    asyncio.create_task(respond())
    asyncio.create_task(respond())


@bot.event
async def on_ready():
    print("Online")



bot.run("Token")

Expected Results

Command should exit with InteractionResponded or better ApplicationContext.respond should switch to followup.

Actual Results

NotFound HTTP exeption is raised.

Your System Information should be your OS's information, py-cord's version info and more information if any. Also, can you show us the full exception traceback?

This happens with me also, when I run code in VS code python debugger using some breakpoints.

I'll recreate the bug when I'm in school.
And will update the issue with the requested information.
