Discord.py - bot sending information about message instead of message

问题

I am trying to make a system where when you react to an emoji, it will send that message (depending on what emoji you reacted with) - to another text-channel, now it is returning this instead of the actual message:

<Message id=733788372891467838 channel=<TextChannel id=733721953134837861 name='admin-bug' position=1 nsfw=False news=False category_id=733717942604398684> type=<MessageType.default: 0> author=<Member id=733720584831369236 name='ReefCraft' discriminator='3102' bot=True nick=None guild=<Guild id=733717942604398682 name="Pumbalo's server" shard_id=None chunked=True member_count=2>> flags=<MessageFlags value=0>>

I have tried making to use .content on the variable, but it still does not work, and it gives me errors: discord.errors.HTTPException: 400 Bad Request (error code: 50006): Cannot send an empty message

Here is my code:

import discord
from discord.ext import commands
import asyncio

TOKEN = '---'
bot = commands.Bot(command_prefix='!!')

emojis = ["\u2705", "\U0001F6AB", "\u274C"]


@bot.event
async def on_ready():
    print('Bot is ready.')


@bot.command()
async def bug(ctx, desc=None, rep=None):
    user = ctx.author
    await ctx.author.send('```Please explain the bug```')
    responseDesc = await bot.wait_for('message', check=lambda message: message.author == ctx.author, timeout=300)
    description = responseDesc.content
    await ctx.author.send('````Please provide pictures/videos of this bug```')
    responseRep = await bot.wait_for('message', check=lambda message: message.author == ctx.author, timeout=300)
    replicate = responseRep.content
    embed = discord.Embed(title='Bug Report', color=0x00ff00)
    embed.add_field(name='Description', value=description, inline=False)
    embed.add_field(name='Replicate', value=replicate, inline=True)
    embed.add_field(name='Reported By', value=user, inline=True)
    adminBug = bot.get_channel(733721953134837861)
    message = await adminBug.send(embed=embed)
    # Add 3 reaction (different emojis) here
    for emoji in emojis:
        await message.add_reaction(emoji)


@bot.event
async def on_reaction_add(reaction, user):
    message = reaction.message
    msg = message.content
    emoji = reaction.emoji

    if user.bot:
        return

    if emoji == "\u2705":
        fixed = bot.get_channel(733722567449509958)
        await fixed.send(msg)

    elif emoji == "\U0001F6AB":
        notBug = bot.get_channel(733722584801083502)
        await notBug.send(message)

    elif emoji == "\u274C":
        notFixed = bot.get_channel(733722600706146324)
        await notFixed.send(message)

    else:
        return

bot.run(TOKEN)

You have to use on_raw_reaction_add(), which returns a RawReactionActionEvent object. You'll be able to get the message_id and to use fetch_message to finally get the embed:

@bot.event
async def on_raw_reaction_add(payload):
    channel = bot.get_channel(payload.channel_id)
    msg = await channel.fetch_message(payload.message_id)
    embed = msg.embeds[0]
    emoji = payload.emoji

    if user.bot:
        return

    if emoji == "emoji 1":
        fixed = bot.get_channel(733722567449509958)
        await fixed.send(embed=embed)

    elif emoji == "emoji 2":
        notBug = bot.get_channel(733722584801083502)
        await notBug.send(embed=embed)

    elif emoji == "emoji 3":
        notFixed = bot.get_channel(733722600706146324)
        await notFixed.send(embed=embed)

    else:
        return

NB: payload.emoji returns a discord.PartialEmoji, comparing it to raw unicode might not work anymore.
