Python 获取discord.ext.commands.errors.CommandInvokeError:

我的Python代码：

@bot.command（别名=[“crole”，“cr”]）
@commands.has_权限（manage_roles=True）
异步def createrole（ctx，*，名称）：
guild=ctx.guild
等待公会。创建_角色（名称=名称）
wait ctx.send（f'Role`{name}`已创建'）
#创建角色错误
@createrole.error
异步def createrole_错误（self、ctx、error）：
如果isinstance（错误，缺少RequiredArgument）：
createrole=discord.Embed(
title=f'Command:{prefix}createrole'，
颜色=不和谐。颜色。来自_rgb（0,0,0）
)
createrole.add_字段（名称='Description:'，值='createa Role'，inline=False）
createrole.add_字段（名称='用法：'，值=f'`{prefix}createrole[rolename][color]`'，内联=False）
createrole.add_字段（name='Example:'，value=f'`{prefix}createrole@parth normal`'，inline=False）
等待ctx.send（f“{createrole}”）
elif isinstance（错误，commands.BotMissingPermissions）：
权限\错误=discord.Embed（描述=f“❌ 我缺少**管理角色**权限”
，color=discord.color.from_rgb（0,0,0））
等待ctx.send（嵌入=权限\错误）

通过发送不完整的命令获取错误>createrole以检查是否发送了my MissingRequiredArgument消息，但获取此错误：
