获取 discord.ext.commands.errors.CommandInvokeError：

Question

我的 Python 代码：

@bot.command(aliases = ["crole","cr"])
@commands.has_permissions(manage_roles = True)
async def createrole(ctx, *, name):
    guild = ctx.guild
    await guild. create_role(name=name)
    await ctx.send(f'Role `{name}` has been created')


#create role error
@createrole.error
async def createrole_error(self, ctx, error):
        if isinstance(error, MissingRequiredArgument):

            createrole= discord.Embed(

                title = f'Command: {prefix}createrole',
                colour = discord.Colour.from_rgb(0,0,0)
            )
            createrole.add_field(name= 'Description:', value= 'Create a Role',inline=False)
            createrole.add_field(name= 'Usage:', value = f'`{prefix}createrole [rolename] [color]`',inline=False)
            createrole.add_field(name='Example:', value= f'`{prefix}createrole @parth normal`',inline=False)
            await ctx.send(f"{createrole}")

        elif isinstance(error,commands.BotMissingPermissions):
            permission_error =  discord.Embed(description = f"❌ I Am Missing **MANAGE ROLES** Permisson"
            ,colour = discord.Colour.from_rgb(0,0,0))
            await ctx.send(embed = permission_error)

通过发送不完整的命令获取错误 >createrole 以检查我的 MissingRequiredArgument 消息是否已发送但收到此错误：

Ignoring exception in on_message

discord.ext.commands.errors.MissingRequiredArgument: name is a required argument that is missing.

During handling of the above exception, another exception occurred:

    ret = await coro(*args, **kwargs)
TypeError: createrole_error() missing 1 required positional argument: 'error'

The above exception was the direct cause of the following exception:
