import lightbulb
from PIL import Image
from io import BytesIO
import requests

plugin = lightbulb.Plugin('Images', 'Create Images')

@plugin.command
@lightbulb.option('user', 'who to create image of',required = True)

async def wanted(ctx: lightbulb.context, user = hikari.User):
    
    slap = Image.open('images\slap.png')
    userAvatarUrl = user.display_avatar_url
    response = requests.get(userAvatarUrl)
    pfp = Image.open(BytesIO(response.content))

    pfp = pfp.resize(100,100)

    slap.paste(pfp,(120,120))
    slap.save('Profile.jpg')

    await ctx.respond(file = hikari.File('Profile.jpg'))    



def load(bot):
    bot.add_plugin(plugin)

I am trying to fetch the user's avatar url but I keep on getting <property object at 0x000001F7E7FE6F70>. I am using Hikari and Lightbulb for this project. I have checked the documentation and tried to figure it out but nothing seems to work.

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

Answer 1

From the code you have supplied I can see that you defined user as an argument to the command function. This is not how options are passed to the command function by default (if you add pass_options=True to the @lightbulb.command decorator then this would work though).

By default command options are stored in an attribute on the context - Context.options . In this case, you would retrieve the user object using ctx.options.user .

By supplying the argument in the command function and having it default to the hikari.User class, when you call user.display_avatar_url , you are just returning the property object attached to the class, not an actual User object.

To fix your code you should do one of the following:

Use ctx.options.user instead of an argument in the command function

@plugin.command
@lightbulb.option('user', 'who to create image of', type=hikari.User)
@lightbulb.command('slap', 'Slap someone')
@lightbulb.implements(lightbulb.PrefixCommand)
async def wanted(ctx: lightbulb.context):
    ...
    userAvatarUrl = ctx.options.user.display_avatar_url
    ...

Or add the pass_options argument to the @lightbulb.command decorator

@plugin.command
@lightbulb.option('user', 'who to create image of', type=hikari.User)
@lightbulb.command('slap', 'Slap someone', pass_options=True)
@lightbulb.implements(lightbulb.PrefixCommand)
async def wanted(ctx: lightbulb.context, user: hikari.User):
    ...

Important: Note how I added a kwarg type=hikari.User to the @lightbulb.option decorator - this ensures that lightbulb converts the option into a User object before calling your command function. If this was omitted, then the option would be a string, not a User object.

NB you are using the synchronous HTTP library requests here which will block your bot while the request is running. You should instead use an async library such as asyncio (included when you install hikari) which will allow other commands to run while the HTTP request is in progress.
