Precondition with Slash Command

How to report precondition failure w/ clash command?
If I use this.error({ message: 'error' }); in precondition, it does nothing.

import { Precondition } from '@sapphire/framework';
import config from '#rootJson/config' assert { type: 'json' };

export class OwnerOnlyPrecondition extends Precondition {
    async messageRun(message) {
        // for message command

        return this.checkOwner(message.author.id);
    }

    async chatInputRun(interaction) {
        return this.checkOwner(interaction.user.id);
    }

    async contextMenuRun(interaction) {
        // for Context Menu Command

        return this.checkOwner(interaction.user.id);
    }

    async checkOwner(userId) {
        return config.owners.includes(userId) ? this.ok() : this.error({ message: 'Only the bot owner can use this command!' });
    }
}

CLI project generates listeners for messages but not for chat input. strange decision.

it's not really a decision. It's just that the examples havent been updated by anyone yet. Set a good example and be the one who fixes it and make a PR to https://github.com/sapphiredev/examples
