[SOLVED] How do I fix a type error (missing annotation) for my discord bot? (Python 3)

How do I fix a type error (missing annotation) for my discord bot? (Python 3)

I keep getting "TypeError: parameter 'reason' is missing a type annotation in callback 'moderation.kick'" whenever I run my bot.

@app_commands.command(name='kick', description='Kicks the member of your choice if you have kick permissions.')
@has_permissions(kick_members=True)
async def kick(s, interaction:discord.Interaction, member:discord.Member, *, reason='None'):
    await interaction.response.send_message(f'User {member} has been kicked.')
    await member.kick(reason=reason)
@kick.error
async def kick_error(s, interaction:discord.Interaction, error):
    if isinstance(error, commands.MissingPermissions):
        await interaction.response.send_message('You don\'t have permission to kick people!')

I don't understand what I'm doing wrong as the default value for 'reason' is a string. I've even rewritten the code to:

async def kick(s, interaction:discord.Interaction, member:discord.Member, *, reason='None') -> str:

This didn't help either. I'm sure it's something simple but any advice would be appreciated!

Solution

As the error points out: Add type annotation to your callback:

async def kick(s, interaction: discord.Interaction, member: discord.Member, *, reason: str = 'None'):
    await interaction.response.send_message(f'User {member} has been kicked.')
    await member.kick(reason=reason)

Normally python should be able to infere the type from the default value, but something in your stack seems to require explicit type annotations.
