AttributeError: 'NoneType' object has no attribute 'id'

Summary

There's an error that have raised when I use the ext.commands.DefaultHelpCommand.

Reproduction Steps

1. Make a normal help command.
2. Type the help command with no arguments to invoke the send_bot_help function.

Minimal Reproducible Code

from discord.ext.commands import Bot, DefaultHelpCommand

bot = Bot(command_prefix=..., intents=..., help_command=DefaultHelpCommand())

Expected Results

The exception raised should not raise when I invoke the help command. But the exception doesn't raise when I invoke cog help, group help or a command help.

Actual Results
