Discord.py 2.3.0聊天命令发送Embed报403权限缺失错误求助

环境 #

Discord.py version: 2.3.0

问题详情 #

• 发送不带Embed的消息一切正常，但发送包含Embed的消息时日志出现403 forbidden错误
• app_commands中实现的Embed可以正常工作，但聊天命令（chat commands）中触发该错误，且已将intents.message_content设置为True

相关代码 #

CountryEmbed类定义 #

class CountryEmbed(discord.Embed):
    def __init__(self, name: str, capital: str, population: int, area: float):
        super().__init__(
            title="Country info",
            colour=discord.Colour.from_str("#a23331"),
            type='rich',
        )

        self.add_field(name='Name', value=name, inline=True)
        self.add_field(name='Capital', value=capital, inline=True)
        self.add_field(name='Population', value=str(population), inline=True)
        self.add_field(name='Area', value=f"{area} m²", inline=True)

聊天命令实现（cog中） #

@commands.command(name='countries')
async def countries(self, ctx: commands.Context, arg: str) -> None:
   ...

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

已尝试的解决方法 #

• 将ctx.send中的embed参数改为embeds：
  修改前：

  await ctx.send(embed=CountryEmbed(name=data['name'], capital=data['capital'], population=data['population'], area=data['area'])
  

  修改后：

  await ctx.send(embeds=[CountryEmbed(name=data['name'], capital=data['capital'], population=data['population'], area=data['area'])])
  

• 发送简化版Embed：

  await ctx.send(content="a", embed=discord.Embed(title='Test', description="ddsdf"))
  

  仅发送了内容"a"，未附带Embed，且日志无错误信息
• 移除Embed中的inline字段
• 查阅官方文档及相关资料，但未找到有效解决方法
