Callback SlashApplicationCommand is missing the self and/or interaction parameters. Please double check your function definition

Question

Hello I am trying to setup cogs in my nextcord discord bot, but i get this warning/error:

MissingApplicationCommandParametersWarning: Callback SlashApplicationCommand ping <function Ping.ping at 0x000002D0F5288F40> is missing the self and/or interaction parameters. Please double check your function definition.

and I also do not get the ability to perform any slash commands in the discord server that I have the bot in.

Here is the following code:

in a moderation folder in the cogs folder I have an __init__.py file with the following:

from nextcord.ext import commands, application_checks
import nextcord

class Ping(commands.Cog, name="Ping"):
    def __init__(self, bot: commands.Bot):
        self.bot = bot

    @nextcord.slash_command(name="ping", description="Slash command that responds with 'Hello World'")
    async def ping(self, ctx: commands.Context):

        print("Received ping")

        await ctx.send("Pong!")

def setup(bot: commands.Bot):
    bot.add_cog(Ping(bot))

Then in a main.py file I have this code:

activity = nextcord.Game(name="with joe mamas balls")
intents = nextcord.Intents.all()

class Overlord(commands.Bot):
    def __init__(self):
        super().__init__(command_prefix="!", intents=intents, activity= activity)

        for folder in os.listdir("cogs"):
            self.load_extension(f"cogs.{folder}")

    async def setup_hook(self):
        for ext in self.cogslist:
            await self.load_extension(ext)

    async def on_connect(self):
        logger.info("OVERLORD IS CONNECTED")

    async def on_ready(self):
        logger.info("OVERLORD IS READY")

if __name__ == "__main__":
    client = Overlord()
    client.run("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")
