Question

I have a poll command in my nextcord bot. I want to add reactions, but when I try the command, It give me this: https://imgur.com/a/p6s3yy5 . How can i fix it?

btw, this is my command:

@nextcord.slash_command(name="yes-no-poll", description="Crée un sondage à deux options", guild_ids=[server])
async def yesno(self, ctx: nextcord.Interaction, poll):
    embed = nextcord.Embed(title=poll, color=nextcord.Color.blue())
    vote = await ctx.response.send_message(embed=embed)
    await vote.add_reaction("<:yes:914969003645091900>")
    await vote.add_reaction("<:no:914969105482809355>")

Please refrain from posting your errors as images. Please paste them directly into the post.

Explanation

As for the code at hand, InteractionResponse.send_message() always returns None, unlike abc.Messageable.send(), which returns a nextcord.Message.

This of course raises an Exception when you try to call add_reaction on a NoneType.

To get around this, you can search the Interaction.channel for a message containing the same Embed as the one you just sent, then add the reaction to that.

Code

@nextcord.slash_command(name="yes-no-poll", description="Crée un sondage à deux options", guild_ids=[703732969160048731])
async def yesno(self, ctx: nextcord.Interaction, poll):
    embed = nextcord.Embed(title=poll, colour=nextcord.Colour.blue())
    await ctx.response.send_message(embed=embed)

    # Loop through channel history and pull the message that matches (should be first)
    message: nextcord.Message
    async for message in ctx.channel.history():
        if not message.embeds:
            continue
        if message.embeds[0].title == embed.title and message.embeds[0].colour == embed.colour:
            vote = message
            break
    else:
        # something broke
        return

    await vote.add_reaction("<:yes:914969003645091900>")
    await vote.add_reaction("<:no:914969105482809355>")
