cog_app_command_error hates me

[aurkaxi]

it doesn't matter if i have cog_app_command_error as a error handler or not. my console showers with bloods
code:

 class Shop(commands.GroupCog, name="shop"):
    def __init__(self, bot:commands.Bot) -> None:
        self.bot = bot

    @app_commands.command(name="testcheck")
    @app_commands.checks.has_role("ShopKeeper")
    async def testcheck(self, interaction: discord.Interaction):
        await interaction.response.send_message("You have the permission to use this command")

    # handle errors disptached in this cog
    async def cog_app_command_error(self, interaction, error):
        if isinstance(error, app_commands.errors.MissingRole):
            return print("i handled it sire")
        else:
            return print("i cannot handle it")

console no matter what:

discord.app_commands.errors.MissingRole: Role 'ShopKeeper' is required to run this command.

expected:
either "i handled it sire" or "i cannot ...."
