discord.py "wait_for" a reaction in a command

Question

I have already written a command. When you execute this command, the bot sends a message to a specific channel. He adds a reaction to this message (an embed by the way). That goes so far. But now, when someone clicks on this reaction, I wanted the bot to respond. In this case, he should send a message to a specific channel. But that doesn't work. There is also no error code, which is supposed to mean that it works, only he doesn't send a message.

@bot.command()
async def buy(ctx, choice):
    channel = bot.get_channel(705836078082424914)
    user = ctx.message.author
    vcrole1 = get(user.guild.roles, id=703562188224331777)
    messagechannel = ctx.message.channel.id
    if ctx.message.channel.id == 705146663135871106:
        if choice == '1':
            if any(role.id == 703562188224331777 for role in ctx.message.author.roles):
                await user.remove_roles(vcrole1)
                await ctx.send(
                    "not important message")
                messtag1 = await channel.send('not important') 
                await messtag1.delete(delay=None)

                embed = discord.Embed(color=0xe02522, title='not important title', description=
                'not important description')
                embed.set_footer(text='not important text')
                embed.timestamp = datetime.datetime.utcnow()

                mess1 = await channel.send(embed=embed)
                await mess1.add_reaction('<a:check:674039577882918931>')

                def check(reaction, user):

                    return reaction.message == mess1 and str(reaction.emoji) ==  '<a:check:674039577882918931>'

                await bot.wait_for('reaction_add', check=check)
                channeldone = bot.get_channel(705836078082424914)
                await channeldone.send('test')

There isn't an error message.

It looks as though your reaction.message == mess1 condition is returning False, and I can't narrow it down as to why that's happening, but I'll edit this if I do.

A way to overcome this would be to evaluate the IDs of the messages:

return reaction.message.id == mess1.id and str(reaction.emoji) == '<a:check:674039577882918931>'

And this will evaluate to True when the bot reacts, so I'd recommend adding another condition to check that the user reacted, if that is what you want the user to do:

return .... and user == ctx.author
