[ERROR] Encountered error on event listener "CorePreChatInputCommandRun"

I'm getting this error repeatedly on an OwnerOnly precondition:

I'm getting this error on an OwnerOnly precondition check:

The precondition works, but this error populates when a not-owner uses the command. Precondition code in the following reply. This is the OwnerOnly precondition, very close to what's demonstrated in the guide: 
import { Precondition } from "@sapphire/framework";

let returnMessageObj = {
    content: 'gotta be the server owner to use this, my friend.',
    ephemeral: true
};

export class OwnerOnlyPrecondition extends Precondition {
    
    async chatInputRun(interaction) {
        // for Slash Commands
        return this.checkOwner(interaction.user.id, interaction);
    }

    async checkOwner(userID, interaction) {
        if (process.env.DISCORD_BOT_OWNER === userID) {
            return this.ok();
        } else {
            interaction.reply(returnMessageObj);
            this.error({ message: 'Only the bot owner can use this command!' });
        }
    } 
}
import { Precondition } from "@sapphire/framework";

let returnMessageObj = {
    content: 'gotta be the server owner to use this, my friend.',
    ephemeral: true
};

export class OwnerOnlyPrecondition extends Precondition {
    
    async chatInputRun(interaction) {
        // for Slash Commands
        return this.checkOwner(interaction.user.id, interaction);
    }

    async checkOwner(userID, interaction) {
        if (process.env.DISCORD_BOT_OWNER === userID) {
            return this.ok();
        } else {
            interaction.reply(returnMessageObj);
            this.error({ message: 'Only the bot owner can use this command!' });
        }
    } 
}
Everything works ... just, as mentioned before, the error spits when the command this is currently used with (Ping) is executed by a not-owner. This leaves me scratching my head. I've poured over the docs, glanced at the source. I don't know what I'm missing. Any help is appreciated!

🤦‍♂️ Why is it that the things I struggle with the most have such a simple--and often overlooked--solution? Thank you. That fixed it.
