Hello, there are multiple ways to add error handling for app commands depending on how you create them, and which style you'd like to use.

For regular app_command package usage there are two ways of defining error handlers, either using the @error decorator on CommandTree:

client = discord.Client(...)
tree = discord.app_commands.CommandTree(client)


@tree.error
async def on_error(interaction: discord.Interaction, error: discord.app_commands.AppCommandError) -> None:
    ...

Or alternatively you can subclass Commandtree and overwrite the on_error method with your own implementation:

class MyCommandTree(discord.app_commands.CommandTree):
    async def on_error(self, interaction: discord.Interaction, error: discord.app_commands.AppCommandError) -> None:
        ...


client = discord.Client(...)
tree = MyCommandTree(client)

If you're using hybrid commands your regular prefix command error handler will be used for app command errors as well.

Hope this helps!
