discord.py; Система предупреждений / ударов

Я новичок в discord.py и делаю бота для личного сервера, и моя команда предупреждения не работает. Вот что у меня сейчас есть:

@client.command()
async def warn(ctx, member: discord.Member, *, reason=None):
    for channel in ctx.guild.channels:
        if str(channel) == "🖊moderation-logs":
            embed = discord.Embed(timestamp=ctx.message.created_at, color=0x00FFFF)
            embed.set_footer(text="Olympia Gaming | Manual Moderation")
        warnid = random.randint(9000000000, 12000000000000)
        post = {
            "guild": ctx.guild.id,
            "member": member.id,
            "warnid": warnid,
            "moderator": ctx.message.author.name,
            "reason": reason,
            "date": str(ctx.message.created_at)
            }

        msg.author = ctx.message.author 
        if member.top_role < msg.author.top_role:
            collection.insert_one(post)
            embed.set_author(name=f"{member} has been succesfully warned!", icon_url="https://cdn.discordapp.com/icons/690937143522099220/34fbd058360c3d4696848592ff1c5191.webp?size=1024")
            embed.add_field(name="Reason:", value=f"{reason}")
            embed.add_field(name="Warn ID:", value=f"{warnid}")
            await ctx.send(embed=embed)
            await member.send(embed=embed)
            embed.add_field(name="Staff Member:", value=f"{ctx.author.mention}({ctx.author.id})")  
            await channel.send(embed=embed)
        elif msg.author.id == ctx.guild.owner_id:
            if msg.author.id == member.id:
                await ctx.send(f" You need your role higher than {member.name}'s to execute this command. ")
            else:
                collection.insert_one(post)
                embed.set_author(name=f"{member} has been succesfully warned!", icon_url="https://cdn.discordapp.com/icons/690937143522099220/34fbd058360c3d4696848592ff1c5191.webp?size=1024")
                embed.add_field(name="Reason:", value=f"{reason}")
                embed.add_field(name="Warn ID:", value=f"{warnid}")
                await ctx.send(embed=embed)
                await member.send(embed=embed)
                embed.add_field(name="Staff Member:", value=f"{ctx.author.mention}({ctx.author.id})")  
                await channel.send(embed=embed)
        else:
            await ctx.send(f" You need your role higher than {member.name}'s to execute this command. ")

Я получаю вот такую ​​ошибку:

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: UnboundLocalError: local variable 'embed' referenced before assignment

Любая помощь была бы признательна.
