`Member.guild_permissions` raises an error with user installed message commands when the bot is not present in the guild's server

[Paillat-dev]

Summary

When using a user-installed message command in a guild the bot is not present in, accessing ctx.author.guild_permissions raises an error

Reproduction Steps

Run the below code, user-install the bot and run the message command on a message in a guild the bot is not present in.

Minimal Reproducible Code

import os

from dotenv import load_dotenv

import discord
import logging

logging.basicConfig(level=logging.DEBUG)

load_dotenv()

TOKEN = os.getenv("TOKEN")

bot = discord.Bot()

@bot.message_command(
    contexts={
        discord.InteractionContextType.guild,
        discord.InteractionContextType.bot_dm,
        discord.InteractionContextType.private_channel,
    },
    integration_types={discord.IntegrationType.guild_install, discord.IntegrationType.user_install},
)
async def test_command(ctx: discord.ApplicationContext, message: discord.Message):
    await ctx.defer(ephemeral=True)
    await ctx.respond(f"{ctx.author.guild_permissions.administrator}")

@bot.listen()
async def on_ready():
    logging.info(f"Logged in as {bot.user.name}")

bot.run(TOKEN)

Expected Results

ctx.author.guild_permissions.administrator being false or ctx.author.guild_permissions being missing.

Actual Results

An error, traceback:
