Issue downloading audio with ytdlp on a raspberry pi

Question

I recently moved my discord bot from replit to my raspberry pi. My discord bot was able to use ytdlp to extract audio from youtube queries. The command to download youtube audio worked perfectly fine on replit, however on the raspberry pi I get the error

a bytes-like object is required, not 'str'

the error is with the following command.

    @app_commands.command(
            name="downloadyoutubeaudio",
            description="Download youtube audio as an mp3 (Takes a few seconds)")
    @app_commands.describe(youtubevideo="The youtube url or search terms")
    async def youtubedownload(self, interaction: discord.Interaction,
                                                        youtubevideo: str):

        await interaction.response.defer(ephemeral=False)
        loop2 = asyncio.get_event_loop()
        try:

            audiodata = await loop2.run_in_executor(
                    None, lambda: ytdl.extract_info(youtubevideo, download=True))

            audiofilename = audiodata['title'] + '.mp3'
            await interaction.followup.send(
                    file=discord.File('youtubemp3.mp3', filename=audiofilename))

            os.remove('youtubemp3.mp3')

specifically this line

audiodata = await loop2.run_in_executor( None, lambda: ytdl.extract_info(youtubevideo, download=True))

Online people have said use the .encode() method however when I use it I get the error cannot use a string pattern on a bytes-like object These two errors seem to contradict. I believe the error is in how my raspberry pi encodes bytes but I do not know how to fix it.

Edit:

When printing the type of youtubevideo, I do get string.

The full error is below

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

EDIT: I just fixed the issue. The problem was with my outtmpl options. Setting 'outtmpl':'youtubemp3.%(ext)s' fixed the issue
