Discord.py how to change server icon with bot command?

Question

Python

I have a code that changes the server name:

@bot.command()
async def rename(ctx):
    await ctx.message.delete()
    guild = ctx.message.guild
    await guild.edit(name='Testing', icon='Тут должна быть ссылка на изображение')

But when I insert a link to an image in the corresponding field, the code returns an error:

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: TypeError: startswith first arg must be str or a tuple of str, not bytes

How to fix it?

Answer 1

with open('image.jpg', 'rb') as f:
    icon = f.read()
await bot.edit_guild(ctx.message.guild, icon=icon)
