Why can't I add a nextcord slash command?

I am getting this error when trying to make a slash command:

`

In name: Command name is invalid“`

The command takes 2 arguments: Tier and Server. Here is the code snippet for the command:

@bot.slash_command(name="sendPlay", description="Play with someone", guild_ids=guildIds) async def sendPlay(interaction: Interaction, tier: int, server: int): await bot.get_channel(PlayReqs).send(f"Join @username in ERLC! If you arrest them you can be banned: Server: Tier {str(tier)}, Server {str(server)}.") await interaction.response.send_message("Sent Public Invite")
Here is the full code:

import nextcord
from nextcord.ext import commands
from nextcord import Interaction, SlashOption, ChannelType
from nextcord.abc import GuildChannel

PlayReqs=1010695004362113094

intents = nextcord.Intents.default()
intents.message_content = True

bot = commands.Bot(command_prefix="!", intents=intents)

I need details so blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah
