Summary

Unexpected AtrributeError on when iterating over guild.chunked() or guild.members

Reproduction Steps

• Load the cog below
• Join a new guild or invoke the event via eval

Minimal Reproducible Code

from discord.ext import commands

class Cog(commands.Cog):
  def __init__(self, bot):
      self.bot = bot

  @commands.Cog.listener()
  async def on_guild_join(self, guild):
      members = await guild.chunk() if guild.chunked else guild.members

      for member in members:
            try:
                # Raises AtrributeError for ClientUser
                if len(member.mutual_guilds) > 1:
            except AttributeError:
                ...

Expected Results

Looking at the code I see no way for this to happen so I'm going to need more information.

Sorry, I see now what you meant. The issue as presented was insufficient due to not showing the error.

The issue stems from the internal User object that the Member is encapsulating being a ClientUser and causing an attribute error since it has no mutual_guilds property for some reason. The way this issue was presented made it seem like Guild.members returned a ClientUser instance instead of a Member, which is impossible.
