使用interactions库的Discord Bot发送Embed报错Invalid embeds求解决

我正在用interactions库开发Discord交互机器人，但无法发送Embed消息，代码片段和导入语句如下：

import interactions
import discord
from interactions import ComponentContext, GuildChannel, OptionType, StringSelectMenu, ActionRow, slash_command, SlashContext, slash_option, Button, ButtonStyle, component_callback, spread_to_rows
from interactions.api.events import Component
bot = interactions.Client()

@component_callback("orderSelect")
async def callbackOrderSelect(ctx: ComponentContext):   
    embed1 = discord.Embed(title="title")
    embed1.add_field(name="embed") 
    
    await ctx.defer(ephemeral=True)
    await ctx.send(embed=embed1)

机器人发送消息时抛出错误：

ValueError: Invalid embeds: <discord.embeds.Embed object at 0x000001F69DD063B0>

完整错误堆栈：

问题原因 #

你混用了discord.py和interactions两个库的Embed类。interactions库有自己独立的Embed实现，它无法识别discord.py的discord.Embed对象，因此判定为无效。

你的另一个项目能正常工作，是因为那个项目基于纯discord.py开发，自然兼容discord.Embed。

解决方法 #

1. 调整导入语句：移除import discord（如果没有用到discord.py的其他功能），并从interactions库导入Embed类
2. 替换Embed实例：将代码中的discord.Embed全部替换为interactions.Embed

修改后的代码示例：

import interactions
from interactions import ComponentContext, GuildChannel, OptionType, StringSelectMenu, ActionRow, slash_command, SlashContext, slash_option, Button, ButtonStyle, component_callback, spread_to_rows, Embed  # 新增Embed导入
from interactions.api.events import Component
bot = interactions.Client()

@component_callback("orderSelect")
async def callbackOrderSelect(ctx: ComponentContext):   
    embed1 = interactions.Embed(title="title")
    embed1.add_field(name="embed", value="字段内容")  # 注意：add_field需要name和value参数，原代码缺少value会报错
    
    await ctx.defer(ephemeral=True)
    await ctx.send(embed=embed1)

额外注意：interactions的add_field方法要求必须传入name和value两个参数，原代码只传了name，即使解决Embed兼容问题后也会触发新错误，所以需要补充value参数。
