Adding a custom Emoji (Discord.py)

Question

Code:

...
@client.event
async def on_message(message):
    if 'e_lastprism' in message.content.lower():
        await message.delete()
        await message.guild.create_custom_emoji(name = ('lastprism'), image = (b'D:\Desktop\diskord BOT\emoji\lastprism.jpg'))
...

After entering, an error emerges: discord.errors.InvalidArgument: Unsupported image type given

Full Error:

Ignoring exception in on_message
Traceback (most recent call last):
  File "C:\Program Files\Python37\lib\site-packages\discord\client.py", line 312, in _run_event
    await coro(*args, **kwargs)

    await message.guild.create_custom_emoji(name = ("lastprism"), image = (b'D:\Desktop\diskord BOT\emoji\lastprism.jpg'))
  File "C:\Program Files\Python37\lib\site-packages\discord\guild.py", line 1504, in create_custom_emoji
    img = utils._bytes_to_base64_data(image)
  File "C:\Program Files\Python37\lib\site-packages\discord\utils.py", line 299, in _bytes_to_base64_data
    mime = _get_mime_type_for_image(data)
  File "C:\Program Files\Python37\lib\site-packages\discord\utils.py", line 295, in _get_mime_type_for_image
    raise InvalidArgument('Unsupported image type given')
discord.errors.InvalidArgument: Unsupported image type given

How can I fix this?

Answer 1

I have not came across this one before but try using .jpg or .jpeg. as it says the wrong image type.

Answer 2

I fix my code with:

with open("D:\Desktop\diskord BOT\emoji\lastprism.png", "rb") as img:
    img_byte = img.read()
    await message.guild.create_custom_emoji(name = ("lastprism"), image = img_byte)
