Slash command member Option does not return user ID for external users when the option is optional

[SlimShadyIAm]

Summary

When you use discord.Member as the type of an Option and you pass in the ID of someone not in the guild when invoking, the argument is parsed to the ID of the user (which is expected). You can then fetch this ID using Client.fetch_user to get the User object. But when the member option is optional (required=False), the argument is parsed to to None instead of the ID even when a valid ID is passed in.

Reproduction Steps

1. Make a command with a discord.Member option
2. Try to execute the command when the option has required=True with the ID of someone not in the server (e.g /cases user:386131861107376128)
3. Print the parameter and you will see the ID
4. Now set required=False, run the command and print the ID again
5. You will see that this time, None is printed instead of the ID. So you cannot have the argument as optional.

Minimal Reproducible Code

@slash_command(guild_ids=[123], description="Show your or another user's cases")
async def cases(self, ctx, user: Option(discord.Member, description="Member to show cases of", required=False)):
    print(user)

Expected Results

The command argument parser returns the ID of the user.

Actual Results

The command argument parser returns None instead of the ID.

Additional Context

The use case for this is, for example, a user info command where you want to be able to display info of:

• users in the server
• users outside the server
• but make the user argument optional so it defaults to the command invoker

not 100% sure, but isn't a discord.Member a discord.User that belongs to that guild? If yes, you can't pass a user that is not in the guild and expect to get a member.

discord.User is not one of the supported option types. If you want to accept IDs of people not in the guild, you have to use discord.Member at the moment and then fetch the user yourself. In that case, the argument you designate to type discord.Member contains the ID so you use that to fetch. This is the only workaround I know of.

Nevermind -- this was an issue on my side.
