Discord.py discord_slash libary cogs error handling

Question

I have one command, but i wanted add a permission, if the guy who dont have permission for banning user the slash send "you dont have a permission for this" I try use:

    @setlang.error
    async def cog_command_error(self, ctx, error):
        if isinstance(error, commands.MissingPermissions):
            await ctx.send("You dont have all permission for this command")

But the output is: discord.ext.commands.errors.ExtensionFailed: Extension 'cogs.Utility' raised an error: AttributeError: 'CogCommandObject' object has no attribute 'error'

Libary: discord.py / discord_slash (in Cog)

Code:

    @cog_ext.cog_slash(name="serverlog",description="Server Log Channel")
    @has_permissions(ban_members=True)
    async def _serverlog(self, ctx, channel: discord.TextChannel = None):

    (code)

    @_serverlog.error
    async def cog_command_error(self, ctx, error):
        if isinstance(error, commands.MissingPermissions):
            await ctx.send("You dont have all permission for this command")
